Fix issue #4913 Assert on svn move [URL] [URL]/subdir.

* libsvn_client/copy.c:
  (try_copy): Always check if target is child of the source when performing
    a move.

* tests/cmdline/copy_tests.py
  (url_move_parent_into_child, wc_move_parent_into_child): New test cases,
    inspired by similarly named _copy_ test cases
  (test_list): Run the new test cases
