Patrick Steinhardt 2a01470891 match-trees: fix leaking prefixes in shift_tree() ...

In `shift_tree()` we allocate two empty strings that we end up
passing to `match_trees()`. If that function finds a better match it
will update these pointers to point to a newly allocated strings,
freeing the old strings. We never free the final results though, neither
the ones we have allocated ourselves, nor the one that `match_trees()`
might've returned to us.

Fix the resulting memory leaks by creating a common exit path where we
free them.
