Contribution page not recorded on recurring transactions, Recurring contribution payments do not create CC or BCC emails or profile notifications

Upon submission of a recurring contribution payment (e.g. from PayPal), no email is sent to addresses:

• Defined in the CC or BCC fields of the contribution page.
• Defined in the notification email address of the profile associated with the contribution page.

OK in 4.7.6. Problem began in 4.7.7 when API3 was introduced for sending contribution receipts/notifications. API is not passed the contribution_page_id which is expected in a subsequent function (CRM/Contribute/BAO/Contribution.php:_gatherMessageValues) to fetch the bcc_receipt and cc_receipt values.
