- Adding a loop test to prevent PROXY based table to loop when repointing on itself.

Browse Source 
- Fix bug causing PROXY on non CONNECT tables to sometimes use the wrong DB.
- Making some more tests in create that were in pre_create not called anymore
  when columns are defined.
- Updating some test results to reflect new warnings.
