fix(RequestQueueV2): implement an isFinished escape hatch if the queue ends up in what seems to be a deadlock state

[vladfrangu]

This still doesn't solve the issue, but it should prevent infinitely hanging actors for now

i'll move this one to draft since we might not need it, let's merge only if #2656 won't help on its own

closing in favor of #2775
