Title: Always enable Pull-to-Refresh, even when UICollectionView is empty

This ensures that the Pull-to-Refresh functionality is always available to address the following situation:

_When a user opens the app for the first time and they do not have an internet connection, the app becomes stuck in an intermediate state that can only be addressed by killing the app and reopening it when they have internet._

This is caused by Pull-to-Refresh's only appearing by default when the UICollectionView has items in it. If there are no items, the app cannot be refreshed (and it does not refresh automatically unless it is explicitly closed and reopened).

This pull-request makes the UICollectionView always scrollable... thus the Pull-to-Refresh is always available, and in the above scenario the user can pull to refresh when their internet connection is regained.
