This is a follow-up to r9401, where the configuration DelayCorrection was replaced by ExtendedFilter. This change also removes the media constraint kExperimentalEchoCancellation which was replaced by kExtendedFilterEchoCancellation in the same CL. Both settings that are now being removed were kept in the code to avoid API breakages. In https://codereview.chromium.org/1167343004, depending code has been updated to avoid breakages.
