🐛 Revoke support for table_name prefixes

Unfortunately, Aerich seems a bit awkward in respecting
Model.Meta.table. Also proxy-tables can not be prefixed at all.

If there is no concise way to prefix all tables of an app, we shouldn't
prefix it at all and leave the collision-problem for the user to keep an
eye on.
