[FIX] crm: team inherits alias, field definition

Before this commit, in some cases, clicking on a crm.lead
triggered a traceback saying "the column crm_team.alias_user_id does not exist"

This was because the field alias_user_id on mail.activity.mixin,
was itself _inherits from mail.alias
In that case, "overriding" the field in the child class is actually
a plain definition of the field, making it "loosing" its related nature

After this commit, there is no traceback anymore
