git-svn fails in prop_walk if $self->{path} is not empty

If url://repo/trunk is the current Git branch, prop_walk strips trunk
from the path name. That is useful as, for example "git svn show-ignore"
should not return results like

    trunk/foo

but

    foo

if svn:ignore for trunk includes foo.

The problem now is that prop_walk strips trunk from the path and then
calls itself recursively. But now trunk is missing in the path and
get_dir fails, because it is called for a non existing path.

The attached patch fixed the problem, by adding the previously stipped
$self->{path} in the recursive call. I tested it with my current
git-svn repository for the commands show-ignore and show-external.
