pgAdmin III commit: Fix crash when opening a dlgType

Fix crash when opening a dlgType

At the opening of the dialog, we do a CheckChange for no reason (at least, I don't see one) and this triggers a crash
becausethe connection variable isn't already set. We could set the connection before the CheckChange but I prefer to
deletethe not-needed CheckChange call. 

Per "report" from Vladimir Kokovic.
