Make sure to set symbol keyboard shifted 

To avoid a corner case of bug#3070963, in toggleShift() method of
KeyboardSwitcher, the shifted symbol keyboard will be set if current
keyboard is symbol keyboard or is not shifted symbol keyboard.

This change also implements mini keyboard cache with WeakHashMap.
