When deleting loose refs, then we also have to delete the refs in the packed backend. This is done by calling `refs_delete_refs()`, which then uses the packed-backend's logic to delete refs. This doesn't allow us to exercise any control over the reference transaction which is being created in the packed backend, which is required in a subsequent commit. Extract a new function `packed_refs_delete_refs()`, which hosts most of the logic to delete refs except for creating the transaction itself. Like this, we can easily create the transaction in the files backend and thus exert more control over it.
