Status “pending payment” via Sofort in test mode with status “payed” #171

Steps to reproduce:

Enable Mollie – SOFORT Banking in test mode.
Put product in cart and use Mollie – SOFORT Banking in Checkout.
In the Mollie payment screen, choose the payment status “payed” and click on “Continue”.

Expected behaviour: Order gets status “processing”.

Actual behaviour: Order gets status “pending payment”. In the order notes it says:

Mollie – SOFORT Banking payment started (tr_asdf1234 – test mode).

Mollie logs:

2017-12-09T15:36:11+00:00 DEBUG mollie_wc_gateway_sofort: Create payment for order 3448
2017-12-09T15:36:11+00:00 DEBUG mollie_wc_gateway_sofort: Payment tr_asdf1234 (test) created for order 3448

Note that everything works as expected when using the Mollie – Bank Transfer method (order gets status “processing”).
