tags: write a separate tags cache file for unfiltered repos
Since we changed the format of the tags cache, we should bump the
filename. Before this patch, "tags" was being used for unfiltered
repositories. Change the naming scheme to be consistent and ensure
that a new cache file is used.
While I was here, I updated the docs to describe the existence of
multiple caches. I also added explicit test coverage for the creation of
the unfiltered tags cache.
