multiqueue: Make sure not-linked streams get woken up

Browse source 
When running in sync-by-running-time mode, pad groups
that have exactly 1 pad and it's not-linked might never
wake up after computing a high time, as the per-pad-group
high time was only recomputed when a pad in the group
advances.

Wake those up using the global multiqueue high-time across
all other groups instead.
