Only test that the dumped YAML strings can be loaded
Only test that the dumped YAML strings can be loaded

* This is a case where we were testing the implementation of the
  YAML library, when all we really care about is that the YAML value
  we persist can be parsed later.

  Just matching on the YAML strings is flawed too, since there can be
  variations in formats between different versions/libraries, so these
  specs will fail when output changes slightly (which was the case
  when testing against JRuby 1.6.0 in --1.9 mode)
