Fix transaction message if PayPal is used

Currently the transaction message looks like this if PayPal is used:

Credit card type:
Credit card last 4:
Processor response: Approved 

I'd expect something like this:

Payment method: PayPal
Payer E-Mail: payer@example.com
Processor response: Approved 

And this for credit cards:

<code>Payment method: Credit card
Credit card type: Visa
Credit card last 4: 1234
Processor response: Approved
