If `createRandomScore()` happened to randomly pick the highest total
score when called with `friend` as the sole argument, that particular
score would not be pink.
`GetScoreByUsername()` would arbitrarily pick the first score for the
user, so in this particular case where a friend had the number 1 score,
the test would wrongly fail.
Fix by checking whether any of the 3 added friend scores have received
the pink colour. Because there is more than 1 friend score in the test,
doing so ensures that at least one of those should eventually become
pink (because, obviously, you can't have two scores at number 1).
