Revert "fetch-pack: add a deref_without_lazy_fetch_extended()"

This reverts commit a6e65fb.

This revert simplifies the next patch in this patch set.

The commit message of that commit mentions that the new function "will
be used for the bundle-uri client in a subsequent commit", but it seems
that eventually it wasn't used.
