AEC3: Ensure that the high-pass filter effect is on when AEC3 is active

Browse source 
This CL ensures that the high-pass filter is on whenever the echo
controller is on. This is important as the echo controller code assumes
that the external high-pass filter is active.

The CL also corrects the ToggleAec unit test (which started failing
after this code change).
