outputselector: Avoid losing the last_buffer when switching

Browse source 
This patch makes outputselector take an extra ref when pushing
the last_buffer to avoid it losing it during the switch function.

This makes resend-latest properly work if the active-pad is changed
during the switch function buffer pushing (on a pad probe, for example).
