[PATCH v3 5/6] reftable: pick either 'oid' or 'target' for new updates

From: Karthik Nayak <karthik.188@gmail.com>

When creating a reference transaction update, we can provide the old/new oid/target for the update. We have checks in place to ensure that for each old/new, either oid or target is set and not both.

In the reftable backend, when dealing with updates without the `REF_NO_DEREF` flag, we don't selectively propagate data as needed. Since there are no active users of the path, this is not caught. As we want to introduce the 'symref-update' command in the upcoming commit, which would use this flow, correct it.
