Revert "[ADD] purchase: average price computation test"

This reverts commit 5f9280e854ac435bdcf903128d5e9d5d0b592070.

These tests have been introduced in 7.0/saas-3, but can no longer be applied in 8.0, as they uses models that do not exist anymore in the new wms.

if such tests do not exist yet in Odoo 8.0, then these tests needs re-work, they cannot be applied like that

[FIX] translate: allow common english 2 chars terms

Before, all isolated (between xml/html tags) two chars words coming from views were not translated (by choice).
But, for some words, allowing them is useful. For instance, the word 'or' located between two buttons.

Raise error on read of a browse object with bad id

Check if id is valid by searching record columns when a key error is raised
If the record has the column, the key error is actually an error on a
missing or inaccessible id.

[FIX] sale: rounded sales team invoiced gauge

The price_total field of the account invoice report is not rounded (it cannot be easily rounded, as this has to be done in the sql view)
In a multi currencies environment, this is possible that the price_total value has a lot of digits
We therefore round it manually, for the gauge of the sales team kanban view
[FIX] Use _unknown model for missing models in relation fields

During a migration of database, it is possible that some custom field
("x_", state is 'manual') are relational to model from a module that is
not provided.

Note: this used to work in Odoo 7.0 but crashed in 8.0.

Closes #3877
[FIX] purchase: remove redundancy in report

The warehouse name and address name is often the same (name of the company).
Remove the name of the address as two warehouse may use the same address.
Fixes #4062
[FIX] sale_stock: product_id_change_with_wh on sale order popup too

product_id_change_with_wh onchange was not anymore called when using the popup form in sale order line.

The behavior was different concerning the product onchange when being in the editable list or in the popup form
For instance, for make to stock products not having enough stock, the warning was displayed when being in editable list, but not in the popup form

This is a regression of rev. 86f785ae1b2741ab67384f3022b971ab638daeb8

[FIX] purchase: replace company_id widget selection by option no_create

For selection fields, name_get calls to resolve the display name are client-side initiated, and will display "Unknown" if the user does not have read access to the selected company. And the reason for using a selection widget in the first place was to prevent inadvertent creation of companies. This is now doable via the no_create option, so we can remove the selection widget.
[FIX] account: 'currency_id' field not defined on account.bank.statement object (correct name is 'currency')
[FIX] web: get conditional user defaults

This is possible to set field conditional defaults, if the field has the attribute "change_default".
The defaults are set by the web client, by calling the method "get_defaults" of ir.values model, when the onchange is triggered on the field on which the condition is.

In 7.0, all onchanges were triggered clientside, one by one. On creation, the defaults of default_get method were pushed in the form, and then, as the values of the fields were changed (from null to the default value), all onchanges on which there was default value were triggered.

In 8.0, onchanges are performed server side, all at once. On creation, the onchange method is triggered by default (wether or not there is a default value for them), for all fields (widget param of method do_onchange of view_forms js is undefined, meaning the onchange is not triggered on a specific field, but on all fields). In such a case, we must call the get_defaults method of ir.values model for all fields (having change_default attribute), in order the conditional defaults to be set in the form view.
[FIX] purchase: replace widget selection by option no_create

[FIX] ensure default addon paths are valid (existing)

User-provided addons paths are checked for existence (and rejected), but
default addons paths are not checked, and blow up when trying to listdir
them (e.g. when http.py tries to load modules).

This is an issue when using Odoo from the distributed tarballs, because
the packaging currently moves all modules to openerp/addons and removes
the root ("main") addons directory.
[FIX] point_of_sale: typo

[FIX] web: ensure one2many field destruction on button cancel

The destruction of one2many fields is forced with the event change:effective_readonly
This revision add the forced destruction for cancel(discard) button as well

Otherwise, one2many fields are not properly destroyed when hitting the button "discard" (from save or discard).
This can be problematic for one2many editable list views (such as invoice lines) if you discard while having a mandatory field not filled in the invoice line: You can't recreate an invoice, the one2many editable list is messed up

Use case: Create an invoice, create a line, leave the description, required field, empty. Then, discard. Then, click on create.
