Tweak the behavior of the MediaSessionStack
This makes the following changes in behavior:
-We will only cache a pending intent for a session if it reaches the
one of the playing states.
-If a previously priority session is removed the next session only
gets priority if it is in a playing state. Otherwise we use the removed
session's PendingIntent.
-The last session to have been playing or to have been added gets
priority after any currently playing sessions, but only if it is still
in the list of active sessions.
-We will only use a session that isn't playing and isn't the most recently
playing/added if we don't have a PendingIntent from the last playing session
to fall back on.
