negativeOrPositive description doesn't match test in part 1

[rachaelcodes]

In the negativeOrPositive function tests, the test is looking for "n is negative" https://github.com/TechforgoodCAST/elm-week/blob/master/part1/syntax-workshop/Main.elm#L203, but the instructions suggest it should return "negative" https://github.com/TechforgoodCAST/elm-week/blob/master/part1/syntax-workshop/Main.elm#L54.
