Do not CC or BCC (Event) Contribution invoice

Contribution Invoices were send to CC and BCC email address that were configured only for Event Confirmation purposes.

When sending an invoice to a user it automatically also got send to the CC and BCC email that were configured for Event Confirmation purposes. While these email addresses are in use to let the event leaders know how many participants can be expected and info on their diet etcetera, it is an unexpected and undesired result when sensitive contribution details (payment arrangements etcetera) are automatically send by CC and BCC to these people.
