Fix RTL language causes history indicator to flip, #4906 (#4907)

This commit will add an awakeFromNib method to the
HistoryProgressCellView class that sets the progress indicator property
userInterfaceLayoutDirection to be leftToRight. This prevents the
indicator from reversing direction when a RTL language is configured.
