Suppress NPE in IMS#onEvaluateInputViewShown().
This is a follow up CL for the previous commit [1], which may have
triggered an unknown bug in either Android Framework or LatinIME.

InputMethodService#mSettingsObserver is initialized in #onCreate() and
cleard with null in #onDestroy(). Hence hitting NPE against it implies
that InputMethodService#onEvaluateInputViewShown() can be called before
InputMethodService#onCreate() or after InputMethodService#onDestroy().
Both possibilities are equaly problematic. Note that this might be a
long-standing issue that just became obvious because of [1].
This CL does not attempt to fix the root cause but just tries to
suppresses the NPE to unblock QA tasks. A proper fix should be made in
subsequent CLs.
