Fix a bug in the legacy recursive commit support, which in most cases
would have always disabled the recursive commit logic.

* subversion/libsvn_wc/adm_ops.c
  (process_committed_internal): Properly detect when to recurse.

* subversion/tests/libsvn_wc/wc-test.c
  (test_legacy_commit1): Remove intermediate state test, as that now
    would fail now.
  (test_legacy_commit2): New function. Testing the slightly newer but also
    long deprecated commit support used around 1.6.
  (test_funcs): Add test.
