[FIX] base: deactivate default language

When a language is deactivated, it may still be referred to in a default value.
A ir.value is created at the database setup to specify the default language.
If a user deactivate the default language but not the ir.value, the creation of
a res.partner would fail as trying to set an unknown value to a selection field.

This commit removes the default value when deactivating the linked language.

The patch is minimal for the bug. A more generic solution would be to verify the
ir.value when calling the default_get method.
This is however a risk of performance degradation (e.g. during a csv import) for
a rare scenario.
The dynamic selection scenario is probably on relevant to res.lang.
A similar problem can occur with many2one fields but is difficult to fix without
performance degradation.
