[JGIT PATCH 11/13] Allow null new ObjectId during RefUpdate.delete

If we are deleting a ref we really don't care about what the
new ObjectId value should be; it just doesn't matter.  If we
didn't set the value we should consider it the same as if we
had a MissingObjectException, which means treat the value as
null and perform a force update test.
