disables warning generated because of using ImportText (obsolete) instead of Textloader.

Perhaps in a future PR, we can update all the unit tests to use TextLoader. I can create a separate bug to track that.

do you think the test should have a check on the results, make sure they are the same all the time, at least. #Resolved
