Replace use of show-ref with name-rev

Browse Source 
Testing showed that show-ref did not accurately determine whether a
git repository contained the given reference.  Testing with name-rev
showed that it did.

Change the HAS_REF determination appropriately to avoid unnecessary
cache updates when using fixed references.
