Make anagram order-independent

[BNAndras]

Related to #410.

I'm sorting the student's results so they can return the anagrams in any order. This only matters when we have a list with more than one anagram so not all tests are touched. Racket's indent-all added some formatting noise, and I also reformatted the candidates for detects three anagrams since that line went a bit long on my screen

This PR touches files which potentially affect the outcome of the tests of an exercise. This will cause all students' solutions to affected exercises to be re-tested.

If this PR does not affect the result of the test (or, for example, adds an edge case that is not worth rerunning all tests for), please add the following to the merge-commit message which will stops student's tests from re-running. Please copy-paste to avoid typos.

Do you want to specify anything in an append about the order not mattering? If not, that's fine, too!

[BNAndras]

Ah, we can just update the append in your PR and merge it in after this is merged.
