Avoid creating user profiles without matching role
The INSTEAD OF triggers on users.list_users did that already, but
profile data coming e.g. via restoring a dump had been added also
if there was no matching database role in the cluster.
This also unifies the errors occuring on creation of users with existing
role names that differed between roles with and without profile before.
Note this is no referential integrity. A dropped role still leaves an
orphaned profile behind.
