[FIX] base: delete parent partner reset use_parent_address

When deleting a partner with some contacts, if the contacts had selected
the "use parent address" checkbox, the address of the contacts was stucked in
readonly mode (no checkbox to disable it).
Disable use_parent_address for orphan partners.

[FIX] stock: compute average price on action_done

The average price computation is now deduplicated and moved to
a separate function called in stock_move action_done.
This makes sure it is always called when a stock.move is
processed, even without going through the partial picking wizard.

[IMP] web: do not fully hide pager in grouped view

When the list view is grouped, the page count should be hidden as irrelevant.
However if it's fully hidden, the limit can no longer be changed.
Instead of hidding the pager, this commit hides the arrows and replaces
the content by the current limit to allow to be changed.

[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.

[FIX] web: user lang has the priority on partner lang

Potentialy, the timezone too.

On item action click (such as menus in More.. and Print..), the data in form view had the priority on user context (through the sidebar_eval_context)

Therefore, if a field "lang" was present in the form view (like in partner form), the web/action/load xmlrpc call was using the partner language instead of the user language.

Example of wrong use case before the fix:
 - Set the user language in French, then go to a partner form of a partner with English set as language
  - Click on any button of the partner form, such as the "Invoices" button, notice that the last item of the breadcrumb is in English, instead of Frenh (the user language)
  - Click on any menu opening a wizard in the More.. dropdown menu, notice that the wizard title is in English instead of French
  - Print any report from the Print dropdown menu, notice that the report file name is in English. If you print the same report for the same partner but from the list view, the report file name is in French.
[FIX] email_template: missing translations in email template

When composing an email based on an email template, some parts of the template
(the result of name_get on fields) were not translated.
This was due to missing language in context when rendering the template.

[FIX] sale_margin: margin handle included taxes for sale

Another fix should probably be build for purchase price, but it isn't that easy, we need to know the partner to which the product has been purchased, as taxes are partner/country dependent.

Besides, included taxes in purchase prices happen less often.
