fetch: Speed up fetch by rewriting find_non_local_tags
When trying to get a list of remote tags to see if we need to fetch
any we were doing a linear search for the matching tag ref for the
tag^{} commit entries. This proves to be incredibly slow for large
numbers of tags. Rewrite the function so that we build up a
string_list of refs to fetch and then process that instead.
As an extreme example, for a repository with 50000 tags (and just a
single commit on a single branch), a fetch that does nothing goes from
~1m50s to ~4.1s.
