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