Fix random delay mode to be random delay not random rate-limited stack.

Browse Source 
Documentation says "Introduces a delay into a flow or rate limits
messages." but this node was doing delay and rate limit in random mode
which doesn't seem that useful. Worse it was a stack not a queue. I
can't think of any sane use cases for that behaviour.
