Add a unit test for EditorInfo#targetInputMethodUser 

This it a follow up CL to my previous CL [1], which introduced
EditorInfo#targetInputMethodUser.

Since EditorInfo#targetInputMethodUser is an @hide API, we cannot
directly its behavior in CTS.  To make sure that it can be transferred
via IPCs , this CL introduces a simple unit test for it in
FrameworksCoreTests.
