[fix] X spells with 2 sides charge +generic mana of 1st side

[Aswan jaguar]

Describe the Bug:
Cut // Ribbons (just coded) it has a bug that it asks for 1 more mana to pay for aftermath. This is a general issue for x spells with two sides
if the first non X mana side has a generic cost then you get prompt to pay
the same amount of generic for second + it's normal cost. This happens when using the method of applying first general mana and then X mana. Which is wrong and causes also other bugs. See previous post.
Crime // Punishment for instance will prompt for extra 3 generic mana for punishment.
Which card did behave improperly?
X spells with two sides that have generic mana in the first side.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
current dev - duel

What exactly should be the correct behavior/interaction?
Pay the mana the card says in it's other side.

Are any other cards possibly affected by this bug?

Fixed in 9d512af

Done by subtracting cards_ptr[get_id(player, card)]->req_colorless from get_updated_casting_cost() for the second side. get_updated_casting_cost() includes the colorless requirement for the first side, so that gets added on to the cost of the second side when calling it for player, card.
