This is more of a principle change than a necessary one.
In lib-jitsi-meet, when a getStats call finishes, the
stats are processed and first emitted (and received by
jitsi-meet) and then processed again for sending to
remote participants. Modifying the stats in place changes
the structure of stats before the second processing,
which maybe be unexpected.

Instead of passing stats through UI then VideoLayout then the
SmallVideo, pass stats directly to what uses it--ConnectionIndicator.
This also bypasses adding the stats to the store, as they do not
seem to be something that needs to be shared or stored app-wide
just yet.
