pgAdmin III commit: Fix backup of a single table

Fix backup of a single table

All schemas were all selected by default, which was wrong. Now, if the user
choose to backup a schema or a table, all schemas are unselected, except the
schema choosen or the schema of the table.

Report from Vladimir Kokovic.
