Legoktm has uploaded a new change for review.

Change subject: Allow presentation models to indicate a notification can't be
formatted
......................................................................
Allow presentation models to indicate a notification can't be formatted
Adds EchoEventPresentationModel::canRender() for notification types to
indicate that something can't be rendered if for example, a page is
deleted.
In that case, the notification is marked as read in a deferred update.
All callers were also updated to check if the notification was formatted
properly.
Bug: T116888
