Following up on r1455946, resolve an assertion in the update-move handling
by detecting not-present children of copies.

* subversion/libsvn_wc/wc_db_update_move.c
  (tc_editor_alter_directory,
   tc_editor_alter_file): Allow expanding over not-present nodes.

* subversion/tests/libsvn_wc/op-depth-test.c
  (print_row): Use a bit more copy&paste friendly output.
  (move_depth_expand): Verify final result.
  (test_funcs): Remove XFail marker from move_depth_expand.

Add another move regression test, showing that incoming deletes are not
always properly moved. In this case it exposes a lower layer.

* subversion/tests/libsvn_wc/op-depth-test.c
  (move_retract): New test.
  (test_funcs): Add move_retract as XFail.
