UICollectionView performBatchUpdates can trigger a crash if the collection view is flagged for layout

[DenTelezhkin]

There's is a known issue with UICollectionView, that crashes application if reloadData call was sent prior to performBatchUpdates method.

Radar: https://openradar.appspot.com/28167779

Sample: https://github.com/PSPDFKit-labs/radar.apple.com/tree/master/28167779%20-%20CollectionViewBatchingIssue

Known workarounds - in terms of DTCollectionViewManager:

• Do not call reloadData method manually, use other methods on MemoryStorage or CoreDataStorage
• Try to group updates into single update block vs calling many blocks all at once - If needed drop to SectionModel level of abstraction.
• You can implement your own CollectionViewUpdater, that calls reloadData instead of calling performBatchUpdates, however this will cost you animations, that will not be performed.

Any help or ideas how to implement maintainable solution are welcomed!
