Fields like `default_foo` still used ir.values although those are system-wide
parameters and should therefore be stored in ir.config_parameter
table.

Also, remove deprecated generation of alias on sales team.
According to usability experts configuring a sales team alias should
be done directly on the sales team view and not through an hidden
and strangely configured settings.
