Condition Rules are not reloaded for Guest Checkout

[androgeus-dev]

When customer is logged in, plugin rechecks the cart totals and coupon rules. It works as described.
But during guest checkout, cart totals are recalculated but the coupon stays active even if the conditions are not valid.

EDIT: Further observation- Its not rechecking conditions when applying Cash on Delivery method. Other payment method is working correctly.
