Previously (until RBAC was introduced) users were not allowed to connect to ClickHouse if user definition referenced a non-existing profile/quota. `DB::Exception: There is no profile 'does_not_exist' in configuration file..`

After RBAC was introduced this behavior changed and now users can connect and they are assigned default profile. This is unexpected and is easy to make mistakes (eg typos) that would give users more privileges than expected (allow_ddl, readonly).
