Fix an edge case in IMS#switchInputMethod()
This CL fixes a long-standing edge case when
InputMethodService#switchInputMethod(String, InputMethodSubtype)
stops working when it should work.
In short, IMMS#mCurrentSubtype can be null even when the IME has
enabled and existing subtype. IMMS#setInputMethodLocked() should just
go ahead to handle the request rather than bailing out.
