 Improve logic for marking at-mention notifications as read

 In previous iterations, at-mention notifications were marked as read in
 the
 following cases:

 - when a user visited his own activity page
 - when a user visited his own mention page
 - when a user visited a single-activity permalink page

 When the new notifications component was introduced in BP 1.9, the old
 notification functions were swapped out one-for-one with the new
 correlates.
 However, this introduced a bug where a logged-out user visiting one of the
 pages listed above would mark at-mention items as read for *all* users
 (due to
 the user_id field being null, and the user_id WHERE clause being excluded
 from
 the UPDATE query).

 We take this bug as an opportunity to narrow the circumstances in which
 at-mention notifications are marked as read. The new system:

 - When a user visits his own mention page, mark all his at-mention
 notifications
   as read
 - When a user visits the permalink page of a single activity item in which
 he
   is mentioned, mark that specific at-mention notification as read

 Fixes #5384
