Scrolling shutter since #40

[crsantos]

Hey 👋
First of all, awesome diff lib.

I started to detect some scrolling shutters when I updated to 0.7.2.

Checking the commits, I see that #40 introduced some setContentOffset calls and I think it may be related to that.

I notice this when I scroll on my UIColllectionView
Sometimes, my scroll is canceled, probably due to a setContentOffset call when a reload is applied when I'm on the middle of a scroll event.

Did anyone notice this on 0.7.2?

I can build sample app to demonstrate if needed.

I also have a problem with the content offset setting. When deleting an item at the bottom of the collection view the collection view automatically updates the content offset which gets reverted by DifferenceKit. Imho, DifferenceKit should only perform the batch updates but not touch the content offset.

@crsantos @iCarambaa
Thank you for your reports.
Agreed.

I will revert its commit to not touching the content offset.
But I'm in state of being bit busy, so please wait until I fixed it ASAP.

I wasn't sure if you needed those setContentOffset lines, but if you don't, I can submit PR removing them
