Multiple Payment received emails being sent (GoCardless)

[Alento]

I am using the GoCardless module and my client is receiving multiple (3) emails when each invoice is paid by GoCardless.

GoCardless sends 4 web hooks to Blesta for each payment. 

The actions triggering the web hooks are:

1. sending one when the payment is created,
2. submitted,
3. confirmed,
4. and paid out.

Blesta is sending identical Payment Received emails at # 2, 3, and 4.

I propose that the fix be that Blesta only sends out an email on receiving the web hook that confirms the payment (#3).

I would have attached images of everything but the forum is broken - at least image uploads are failing.
