Spree::Promotion::Actions::CreateItemAdjustments#promotion_credit_exists?

Tells us if there if the specified promotion is already associated with the line item
regardless of whether or not its currently eligible. Useful because generally
you would only want a promotion action to apply to line item no more than once.

Receives an adjustment +source+ (here a PromotionAction object) and tells
if the order has adjustments from that already
