[PATCH v4 4/5] remove_subtree(): test removing nested directories

[Daniel Ferreira <bnmvco@gmail.com>]

Test removing a nested directory when an attempt is made to restore the
index to a state where it does not exist. A similar test could be found
previously in t/t2000-checkout-cache-clash.sh, but it did not check for
nested directories, which could allow a faulty implementation of
remove_subtree() pass the tests.
