<h3>Log Message</h3>
<pre>Notifications: Invalidate cache when a notification is updated.
Object caching was added to the notifications component in <a href="http://buddypress.trac.wordpress.org/changeset/7813">r7813</a>.
However, the cached item was not invalidated whenever a notification
is updated (either by using one of the marked as read functions or via
using the BP_Notifications_Notification::update() method).
This commit invalidates the cache directly in the update() class
method and adds a unit test.
See <a href="http://buddypress.trac.wordpress.org/ticket/5377">#5377</a></pre>
