When the accessibility mode is on, or a hardware keyboard is attached to
the device, it will disable the scroll to load functionality on History
activity, and a footer contains MoreProgressButton
(browser/ui/widget/MoreProgressButton) will be added and bounded with
HistoryAdapter#loadMoreItems.

Unit test for HistoryAdapter and HistoryActivity is also included.
