[PepperBridge] fix and discussion (#2383)

* [PepperBridge] Fix some Notice for expired items

Some expired iteams are not identical to normal items for the title and
URI, so they got a special handling to remove PHP Notice.

The "most commented" sorting option was removed and show now some forum.
So it was removed.

With DealabsBridge, MydealsBridge and HotUKDealsBridge, you can monitor
a discussion for new comments, excluding or not post without URL
