Changed fizz.py in the active pilot repo (n1_fizzbuzz__C__r1/repo/fizz.py): moved the `i % 15` check ahead of the `i % 3` and `i % 5` checks, so multiples of 15 now return "FizzBuzz" instead of falling into the "Fizz" branch.

Tests pass: `python3 -m unittest discover -s tests -t . -q` reports OK (1 test).
