Fix TableViewCell skeleton not being removed & automaticNumberOfRows reference

[harrisonsj]

Summary

• For UITableView the skeleton is added/removed to visibleCells, visibleSectionHeaders & visibleSectionFooters, however when hideSkeleton is called with reloadDataAfter: true this can leave some cells with the skeleton still active because visibleCells may not contain the same number of cells as when showSkeleton was called (i.e. when the estimatedRowHeight is significantly less than the actual row height). Changed to add/remove skeleton to all TableView subviews. Fixes The skeleton view do not complete hide. #399.

• Fix automaticNumberOfRows reference error from PR Add SkeletonCollectionDataSource.automaticNumberOfRows Constant #401.
