ls-refs: use repository parameter to iterate refs

The ls_refs() function (for the v2 protocol command of the same name)
takes a repository parameter (like all v2 commands), but ignores it. It
should use it to access the refs.

This isn't a bug in practice, since we only call this function when
serving upload-pack from the main repository. But it's an awkward
gotcha, and it causes -Wunused-parameter to complain.

The main reason we don't use the repository parameter is that the ref
iteration interface we call doesn't have a "refs_" variant that takes a
ref_store. However we can easily add one. In fact, since there is only
one other caller (in ref-filter.c), there is no need to maintain the
non-repository wrapper; that caller can just use the_repository. It's
still a long way from consistently using a repository object, but it's
one small step in the right direction.
