viz: Assign temporary refernces with --enable-viz.

Fix the logic that decides whether or not to assign temporary references
in HostFrameSinkManager. This fixes temporary references not being
assigned owners when running with --enable-viz in desktop Chrome. Add a
test to verify temporary references are assigned with a remote
FrameSinkmanager.

Also fix some places in HostFrameSinkManager where |frame_sink_manager_|
and |frame_sink_manager_impl_| were mixed up.
