The delay with jitter can be equal to 0

[Corvus278]

in the fullJitter function, a random number is used to calculate the delay, which is multiplied by prevDelay*e^attemptNumber.
But Math.random() can return 0, and then the total delay before repeating the request will be 0.
Is this a bug, or ok?

@Corvus278 Rather than returning the delay, this function merely returns the jitter. As such, the jitter may be zero, but that would not result in the delay being zero.
