Unlike svnadmin_tests.reflect_dropped_renumbered_revs() -- the test on
which it is modeled -- svnrdump_tests.reflect_dropped_renumbered_revs() 
creates its "toplevel" subdirectory *after* the initial load, not
before.  As such, the expected mergeinfo is a bit different in this
case (off by a single revision).

* subversion/tests/cmdline/svnrdump_tests.py
  (reflect_dropped_renumbered_revs): Correct expected output, and
    remove @XFail() decorator.
