Fixed 2 project tests

- now that the recursive search for xliff files works again, the
  tests were accidentally finding all of the xliff files and therefore
  not producing the new strings files, which is what they trying to test!
  Solution is to point those tests at directories that do not contain
  the translations they were looking for, causing them to create the
  new strings files again
