Scoring 2 sets with 1 puck slide will cause the first set animation to be incorrect

[klapstoelpiloot]

When 1 puck slide is used to score 2 sets (2 pucks enter gates which each finish a set), then the set animation will show twice. However, the first animation is for the same set index as the second animation.

This bug is caused due to the set index to animate is set directly on the setanimation object in the PlayingState (line 249), but the actual animation is queued to be displayed at a later time. This bug does not cause the score to be counted incorrectly.
