Subject: [PATCH] Make test_emoji about 500ms faster.

The test_emoji test makes sure that we build the correct image
tag for all of our emojis.  It's the same underlying algorithm
for all 800+ images, so we now test it in O(1) times instead
of O(N) time.  Randomly sampling the emojis makes the tests
slightly non-determinisitic in a theoretical sense, but not in
a practical sense.
