Simplify IMMS#showInputMethodMenu() a bit

SwitchingController#getSortedInputMethodAndSubtypeListLocked() is
anyway called to determine what items should be shown on the IME
switcher dialog, whether there is no item to show or not should also
be determined by the same method.  There is no need to call
getExplicitlyOrImplicitlyEnabledInputMethodsAndSubtypeListLocked()
just to check whether its result is empty or not.
