Fail-fast cases of blocking InputConnection APIs

This CL finally adds regression tests for our prior CL [1], which
implemented fail-fast mode for blocking InputConnection APIs based on
IInputMethod.unbindInput() async signal from IMMS to IMS.

Basically what that CL [1] implemented is that once InputMethodService
receives IInputMethod.unbindInput(), subsequent calls on blocking
InputConnection APIs to the already-unbound IME client should
immediately fail.  This CL ensures that such a behavior is correctly
implemented.
