Revise test for issue #4367 'merge to shallow WC, repeat merge to infinite
depth WC is broken'.

* subversion/tests/cmdline/merge_tests.py
  (merge_to_empty_target_merge_to_infinite_target): Revise the test to
   mimic the user reported bug described here,
   http://svn.haxx.se/dev/archive-2013-05/0220.shtml, rather than the "bug"
   described in
   http://subversion.tigris.org/issues/show_bug.cgi?id=4367#desc2, which 
   isn't a bug at all (as discussed here
   http://svn.haxx.se/dev/archive-2013-05/0220.shtml).
