Conley Owens 565480588d Check for existence of refs upon initial fetch
When we do an initial fetch and have not specified any branch etc,
the following fetch command will not error:
git fetch origin --tags +refs/heads/*:refs/remotes/origin/*

In this change we make sure something got fetched and if not we report
an error.

This fixes the bug that occurs when we init using a bad manifest url and
then are unable to init again (because a manifest project has been
inited with no manifest).
