Show refs for repos with tags (or other "unexpected" refs)

[mattwynne]

If the code in handleGetRefs throws any kind of error, we just return an empty Refs() object.

The error swallowing was presumably for dealing with calls to show-refin empty repos, but it's also swallowing errors parsing refs.

Need to change this so the try/catch block is only around the call to show-ref and not the parsing bit, so that parsing errors are still thrown.

Not stale, this is important!

We've got to fix this. It won't take long and it will exclude lots of user's repos.

I've cleaned up this code and it seems to be working now. Closing.
