refs: fix potential free of uninitialized variable The `signature` variable in `git_reference_rename` isn't initialized and neither does `git_reference__log_signature` always do. So if the latter function fails, we'll call `git_signature_free` on this unininitialized variable. Fix the issue by initializing the pointer with `NULL`.
