[FIX] google_{account|calendar}: fix synchro

- no more tracebacks when trying to sync more than once with Google Calendar
- no more context hacks, explicit return of `ask_time`.

(Closes #1588)
[FIX] base : context evaluation with active_id server side. It now keeps the active_id in case of a refresh.
[FIX] Fixed the issue of calendar view reload events inconsistency, when the slow create popup creates event through any form button which is kind of object, action or workflow at that time events are reloaded but still button action is not called like workflow is not triggered and hence state of the event is still not changed and due to domain newly created event is filtered, note that events are refetched when create_completed is triggered and create_completed is triggered right after creation of record, but there are case where some form button changes state of the record and it requires to refetched for example we have scenario in mrp order planning where Confirm Production creates event but before workflow is triggered and state of the event is changed, events are reloaded and newly created event will not returned because of domain.
[FIX] test_new_api: missing parent menu
[FIX] account: reconcile: no useless revalidation

Avoid revalidating the complete account moves
that contain the lines being reconciled.
The reconciliation does not change the validity
of those moves anyway.
This represents a very important speed up of
reconciliation when moves with several hundred
lines are involved.
[FIX] stock: inventory lines with no production lot: compare with correct stock level

Inventory lines without production lot number should
be compared with the stock level of products without
a production lot. Otherwise the final result of a
validated inventory is wrong as soon as there are
lines with and without production lot for the same
product.

Adds corresponding regression test.

[FIX] models: onchange on new records do not nullify fields from _inherits records
[FIX] point_of_sale: field date of report.pos.order should be a datetime

The date_order field of the pos.order is a datetime, not a date
As, in report.pos.order, the date field is related to date_order of the pos.order

We usually do not commit fixes altering the model fields structure in 7.0, but this one is retro-compatible, as the database structure won't change
[FIX] models: stored func fields computation on one2many write

On one2many fields writing in an existing record (not when creating new record), the computed stored fields of the one2many were not re-computed correctly
Computed stored fields were marked as modified only if no_store_function was not set to True in the context. no_store_function is set when writing one2many records on an existing record.
Now, these computed stored fields are marked as to be recomputed, but are recomputed later, at the end of the existing record write
[FIX] models: `_convert_to_write()` shall not return `NewId`

The result of _convert_to_write() is intended to be pass directly to
`write()` or returned to the client (`onchange()` and `default_get()`.
`NewId` is as special value that must not be stored into the database
or exposed to the client.

[FIX] product: make sure unlinked product still exists

When uninstalling/updating a module, we may execute unlink method on product.template before product.product. In such cases, the product is already removed after removeing the template (_inherits) and the chained unlink of the product would fail (traceback when browsing).
[FIX] point_of_sale: the product name field changed to display_name to include variants information, this should be reflected in searches as well.
