A Change to the Way Broadcasts Give Access to Pages in Spaces

I've changed the logic around using broadcasts to release pages in spaces.

Until now, there were a couple of challenges with this, which basically came down to the fact that if the person wasn't receiving the email, they didn't get access to the page either.

That would typically happen in three cases:

1. The participant has opted out of emails for this product
2. The participant has turned on "Do Not Contact"
3. The broadcast is sent to two different products, and the person is participating in both—in this case they'd only get access via one of the products, which is fine until the one that has the access is canceled

I've changed it now so that we grant access to the pages, regardless of the settings for whether or not they want to receive emails, and before removing duplicates.

That should make granting access to auto-published pages in spaces using Broadcasts much more robust.
