git svn: fix fetch where glob is on the top-level URL

In cases where the top-level URL we're tracking is the path we
glob against, we can once again track odd repositories that keep
branches/tags at the top level.  This regression was introduced
in commit 6f5748e.

Thanks to Daniel Cordero for the original bug report and
bisection.
