Removes the nonEmptyOrFail function in favour of making use of OverloadedLists after changes in #1231

[danbroooks]

These were also causing some type ambiguity errors, where with OverloadedLists we want to use this value here both as a [Text] and NonEmpty Text, so I have opted to re-writing the test with literals rather than trying to re-use the values. I've tried to include some more realworld looking values too while changing things here.
