psql: Fix tab-completion after GRANT/REVOKE on LARGE OBJECT and FOREIGN SERVER.

Previously, when pressing Tab after GRANT or REVOKE ... ON LARGE OBJECT
or ON FOREIGN SERVER, TO or FROM was incorrectly suggested by psql's
tab-completion. This was not appropriate, as those clauses are not valid
at that point.

This commit fixes the issue by preventing TO and FROM from being offered
immediately after those specific GRANT/REVOKE statements.
