REPACK CONCURRENTLY: fix processing of toasted tuples

In order to process tuples inserted or updated while REPACK executes, we
write those tuples to disk and later restore them; however, some forms
of toasted tuples were not being processed correctly.  Fix that.

Also expand the tests a bit for better coverage.
