receive-pack: allow deletion of corrupt refs
Occasionally, in some setups (*cough* forks on repo.or.cz *cough*) some refs go stale, e.g. when the forkee rebased and lost some objects needed by the fork. The quick & dirty way to deal with those refs is to delete them and push them again. However, git-push first would first fetch the current commit name for the ref, would receive a null sha1 since the ref does not point to a valid object, then tell receive-pack that it should delete the ref with this commit name. delete_ref() would be subsequently be called, and check that resolve_ref() (which does _not_ check for validity of the object) returns the same commit name. Which would fail. The proper fix is to avoid corrupting repositories, but in the meantime this is a good fix in any case. Incidentally, some instances of "cd .." in the test cases were fixed, so that subsequent test cases run in t/trash/ irrespective of the outcome of the previous test cases.
