Fix repo mirror with --current-branch

Browse Source 
Before a2cd6aeae8, "repo mirror with --current-branch" fetches git data
using command
    git fetch --progress --update-head-ok cros --tags
No refspec is specified, thus it fetches default refspec, which is +refs/heads/*:refs/heads/*

After a2cd6aeae8, the fetch command became
     git fetch --progress --update-head-ok cros --tags +refs/tags/*:refs/tags/*
It did not only add tags refspec, but also suppressed the fetching of default refspec.

In other words, repo mirrors doesn't work if current_branch_only=True.
This CL explicitly adds the default refspec to command line if none is
specified.
