Before this CL, we didn't check whether the remote session existed
in the list before. If priority of remote session is higher than
local session, it causes us to return the local session even if
the list has a remote session.
This CL uses a list to cache package names of remote sessions.
If the local session has the same package name of the remote session
then don't return the local session.

Before this CL, output switcher will show 2 media sessions when
some apps are remote playing. The root cause is some apps will
also create local media sessions when they cast media to remote
playing.
This CL add condition to only show remote sessions on output switcher
if apps both have remote and local sessions.
