css fix of remove icon and Fixed a bug where the discount coupon applied...

... ‘disappeared’

 when changing the quantity between enrollment vs reg code cart types.
Yea, that's the design from Product. Qty=1 is a PaidCourseRegistration as you are enrolling yourself. Qty > 1 means "buying Registration Codes" (and the purchaser is not enrolled post transaction). That if/else was existing code. As I understand, the bug was that in this transition of quantity, if a coupon code was already applied, it needed to be transfered to the new OrderItem type.
