commit: avoid possible use-after-free When extracting a commit's signature, we first free the object and only afterwards put its signature contents into the result buffer. This works in most cases - the free'd object will normally be cached anyway, so we only end up decrementing its reference count without actually freeing its contents. But in some more exotic setups, where caching is disabled, this can definitly be a problem, as we might be the only instance currently holding a reference to this object. Fix this issue by first extracting the contents and freeing the object afterwards only.
