Fix random sha1 in error message in http-fetch and http-push

Browse Source 
When a downloaded ref doesn't contain a sha1, the error message displays
a random sha1 because of uninitialized memory. This happens when cloning
a repository that is already a clone of another one, in which case
refs/remotes/origin/HEAD is a symref.
