Fix mark-and-restore-skipping test case to not be a self-join.

There isn't any good reason for this test to be a self-join rather
than a join between separate tables, except that it saved a couple
of SQL commands for setup.  A proposed patch to optimize away
self-joins breaks the test, so adjust it to avoid that happening.
