This is a small preparation to consolidate RemoteException handling
out from InputConnectionWrapper.
With this CL, InputConnectionWrapper no longer early-exits when a
RemoteException is thrown but just falls through to IME tracing logic.
By making this small change, the next CL [1] can split out
RemoteException handling from InputConnectionWrapper as a pure
refactoring.
Anyway neither users nor developers can observe this change unless
they are carefully checking IME tracing result when the IME target app
is being killed.
