iOS6, 7, and 8 each have different ways of handling line breaks in accessibility labels.  Revised the solution to work across all three.
Don't return from waitForCellAtIndexPath:inTableView: until scrolling completes.
Fix picker test for iOS8 where accessibility values dropped their index. (Did someone else get it?)
Increase delay after orientation change.  Looks like iOS8 is slower here.
Let things settle because the Travis had an inconsistent failure.
