Missile award incorrectly relights after mode ends

[clempo2]

The rule sheet says: if missile award is lit when multiball starts, missile award is disabled but it is remembered and it relights automatically after the last concurrent multiball ends. This works, but afterwards, every chain mode ending incorrectly relights the missile award. This defect continues until the ball ends or another multiball is started with missile award already turned off.

This happens because the flag missile_award_lit_save is not cleared when relighting missile award.
