Trying to address the cleanup issue reported by Brane in
http://svn.haxx.se/dev/archive-2013-11/0198.shtml

Although I cannot reproduce the problem, global pool cleanups
in apr_terminate() are known to be fragile.  Thus, run cleanups
explicitly long before terminating the application.

* subversion/tests/svn_test_main.c
  (do_tests_concurrently): Don't run cleanup here.
  (main): Run cleanups in the same order as in non-threaded mode
          making sure that the apr_thread_pool terminates before
          shutting APR down.
