Fix 6398209: Fix glitch in chevron animation in MultiWaveView

This fixes a glitch caused by clearing the array of chevrons before
stopping the associated animations. The old animations were allowed to
complete which caused chevrons to move around erratically because they
were being controlled by multiple animators.
