New tests are added to avoid regressions when the ContentHandler facility
is introduced.

Changeset 3: use tablesUsed to allow database cleanup after test, as per
             Aaron's suggestion.

Changeset 4: use array_merge instead of +=.

Changeset 5: trying dumber rollback test to see of jenkins likes it better.
