Fix streaming notifications not using quick filter logic (#18316)

Fixes #18309

The quickFilter logic was used on display and to request new notification
pages, but not for live updates. The main issue this caused is bump the unread
notifications count regardless of the quickFilter setting.

Since notifications are re-fetched when changing quickFilter settings, it is
safe to drop live notifications that do not match the selected filter.
