[Qt] prepare paymentservertests for new unit tests

- add a second PaymentRequest Test CA certificate to paymentrequestdata.h
  (serial number f0:da:97:e4:38:d7:64:16) as caCert2_BASE64
- rename existing Test CA certificate to caCert1_BASE64
- rename existing payment request data to know they belong to
  caCert1_BASE64
- update comments to reflect the changes and add a missing comment to one
  of the payment requests
