test_repository_tool: Add missing clear_all flag

Currently TestTimestamp creates custom databases but only clears the
default ones. This means next create_*db() call will fail meaning every
test after this one will fail (currently TestTimestamp happens to be
last but the effect can be seen by renaming it to TestATimestamp).

Also remove the clear_*db() calls from TestRepository::Setup(): they are
likely to be a workaround for a similar problem earlier (earlier test
failed to cleanup).
