[PATCH 07/16] refs: add repository argument to get_main_ref_store




Add a repository argument to allow the get_main_ref_store caller
to be more specific about which repository to handle. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.
