toArray() duplicates items for each subscription

[martinhrvn]

RxJS version:
5.5.2

Code to reproduce:

const count = Rx.Observable.interval(1000).take(10)
const countArray = count.toArray()
countArray.subscribe(i => console.log(i))
countArray.subscribe(i => console.log(i))

Expected behavior:
In both cases an array with 0 to 9 is returned:

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Actual behavior:
The values returned are duplicated for each subscription:

[0, 0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9]
[0, 0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9]

Additional information:
This is a regression from 5.4.3, where the values are as expected

@kwonoj I believe your PR the other day fixed this.
