files-backend: make reflog iterator go through per-worktree reflog

refs/bisect is unfortunately per-worktree, so we need to look in
per-worktree logs/refs/bisect in addition to per-repo logs/refs. The
current iterator only goes through per-repo logs/refs.

Use merge iterator to walk two ref stores at the same time and pick
per-worktree refs from the right iterator.

PS. Note the unsorted order of for_each_reflog in the test. This is
supposed to be OK, for now. If we enforce order on for_each_reflog()
then some more work will be required.
