able to cover more testing scenarios
Currently, its hard to implement test suite for payments because
mockpayments is on to high level and we cannot emulate many things e.g.
adding credit card. This change is first to be able to add mock for
Stripe client and do more granular tests.

The billing history currently shows the Total amount from the Stripe
invoice. In fact, this value is just the amount deducted from the Stripe
balance. It does not reflect any deduction from promotional coupon or
bonus credits.
This patch adds the deducted amount form the promotional coupons and
bonus credits to the displayed amount in billing history. This way
customers have better understading of the total amount deducted from
their account balance on the satellite.
