matchers: rewrite RepoPathTree::to_visit_sets() to not depend on is_dir flag

Browse source 
The is_dir flag will be removed soon. Since FilesMatcher doesn't set is_dir
flag explicitly, is_dir is equivalent to !entries.is_empty(). OTOH,
PrefixMatcher always sets is_dir, so all tree nodes are directories.
