Sync exercises to problem-specifications

[BNAndras]

I noticed several slugs are missing tests. Looking at roman-numerals, I also noticed some tests where the inputs and outputs line up with tests from problem-specifications but the comments describe something different. I'll keep an eye out for those as well.

• allergies
• anagram
• armstrong-numbers
• collatz-conjecture
• gigasecond
• matching-brackets
• phone-number
• roman-numerals
• say
• sublist
• word-count

@ErikSchierboom, can I get approval for the five open PRs linked here? You can skip the PR for say since that one's not ready.

[ErikSchierboom]

@BNAndras Sure!

[BNAndras]

Picking this back up. Anagram will need a second PR and then I'll go through say and word-count.

[BNAndras]

I'm leaving say alone for now. I want to restructure the test suite to resemble the other exercises. However, the test suite is broken into the four separate stepX functions while the problem specifications use a single say. I don't want to break any solutions so I want to make sure the right tests go with the right step function. The exercise likely needs to get boosted in difficulty level as well.
