[test]solemn vigil does not restore its original cost after one's turn ends

[tonyyyye]

omit the former steps.

        game.end_turn()
        assert vigil3.cost == 5
E    AssertionError: assert 0 == 5
E     +  where 0 = <Spell ('Solemn Vigil')>.cost

in collectible.py
we have this:

class BRM_001:
	"""Solemn Vigil"""
	play = Draw(CONTROLLER) * 2
	cost_mod = -Attr(GAME, GameTag.NUM_MINIONS_KILLED_THIS_TURN)

@jleclanche was it designed as the script or am I understanding this in a wrong way?

Find out the problem.
game.players.minions_killed_this_turn needed restoring when game.end_turn

Think I've solved this by #459
