refs API: make expand_ref() & repo_dwim_log() not set errno 

The use of these two is rather trivial, and it's easy to see none of
their callers care about errno. So let's move them from
refs_resolve_ref_unsafe() to refs_resolve_ref_unsafe_with_errno(),
these were the last two callers, so we can get rid of that wrapper
function.
