Fix send-pack for non-commitish tags.

Again I left the v2.6.11-tree tag behind.  My bad.

This commit makes sure that we do not barf when pushing a ref
that is a non-commitish tag.  You can update a remote ref under
the following conditions:

 * You can always use --force.
 * Creating a brand new ref is OK.
 * If the remote ref is exactly the same as what you are
   pushing, it is OK (nothing is pushed).
 * You can replace a commitish with another commitish which is a
   descendant of it, if you can verify the ancestry between them;
   this and the above means you have to have what you are replacing.
 * Otherwise you cannot update; you need to use --force.
