Payment webhook failing with default Mollie module installed but disabled

[Rhytz]

The readme mentions

Each module requires the by default included mollie module to be present (may be deactivated) as the new classes extend the mollie class

But when the default module is disabled, users will receive the following error after their payment, and the webhook will not succeed, resulting in the invoice not being marked as paid:

error loading configuration payment provider configuration not found in database

I believe the modules have to be activated once to add some entries to the database. Once that's done they can be disabled.
