UI: Don't use activeRefs to determine if active

Due to certain design changes for delay, it's better to simply determine
whether outputs are active via booleans rather than an activeRefs
variable, which could get decremented more than once if say, the signal
for stopping the stream gets called more than once for whatever reason
(which may happen in the case of delay due to the way delay works)
