[PATCH 2/2] refs: switch for_each_replace_ref back to use a ref_store

[Stefan Beller <sbeller@google.com>]

This effectively reverts commit 0d296c57ae (refs: allow for_each_replace_ref
to handle arbitrary repositories, 2018-04-11) and 60ce76d3581 (refs: add
repository argument to for_each_replace_ref, 2018-04-11).

The repository argument is not any special from the ref-store's point
of life.  If you need a repository (for e.g. lookup_commit or friends),
you'll have to pass it through the callback cookie, whether directly or
as part of a struct tailored to your purpose.

So let's go back to the clean API, just requiring a ref_store as an
argument.
