ostree: Use --touch-if-changed

Browse Source 
There are three different cases:

 * we expect commitid and it's there
 * we expect commitid and it's missing
 * we don't expect commitid

This patch helps differentiate between the second two. In former one we
should report an error and mark the phase as failed. The latter is
perfectly fine and no error should be reported
