Magento 2.3 setup:install

[tschirmer]

Under setup install with the module enabled, we're getting:

[RuntimeException] Source class "\Fontis\Australia\Model\Payment\BPAY\CustomerGroupAccessCheck" for "Fontis\Australia\Model\Payment\BPAY\CustomerGroupAccessCheckFactory" generation does not exist.

@tschirmer Would you be able to provide more information about the steps you took to install the code in the first place?
