Merge branch 'jx/do-not-crash-receive-pack-wo-head' into maint

An attempt to delete a ref by pushing into a repositorywhose HEAD
symbolic reference points at an unborn branch that cannot be
created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
points at refs/heads/a) failed.

* jx/do-not-crash-receive-pack-wo-head:
receive-pack: crash when checking with non-exist HEAD
