mail.thread mixing class defines several methods used in notification process
that are not specific to mail.thread enabled models. It means some models
could override it while some other models do not even have a direct access
to that method.
When calling those methods we have to manually check for method being
available on a record or call a default implementation from mail.thread
even if the model does not inherit from the mixin.
In this commit we propose to hide this check in generic wrappers located
in mail.thread class. It checks for method existence on record and call
the model-specific implementation or falls back on standard behavior. It
allows to be sure the right method is called.
Functionally behavior should stay globally the same. However when updating
some addons code has been updated. Previous code could lead to records not
having correct alias which should not be the case anymore. This commit is
linked to task ID 47934.
