DO NOT MERGE: Don't let NotificationEntryManager keep around old RankingMaps

When a notification becomes lifetime-extended, NotificationEntryManager
was holding onto the RankingMap that was passed at the time of removal
of _that_ notification, and using it again in the
NotificationSafeToRemoveCallback. The problem here is that when
onSafeToRemove gets called, it was passing that same stale ranking map
to removeNotification, which caused any notification that arrived in the
intervening time to get improperly ranked.

This fixes an issue where any notification that arrives while another is
lifetime-extended can get the wrong ranking applied to it, causing
trouble later in time such as mis-ranking and mis-sorting until the next
update from system server.

Test: atest SystemUITests
Test: manual - Post a FGS notification and immediately cancel, then post
a regular notification and wait for the FGS notification to dismiss.
Note that the regular notification keeps showing in the status bar.
