Remove remaining direct references to kExperimentalAppBanners

crrev.com/786357 replaced references to kExperimentalAppBanners with
calls to IsExperimentalAppBannersEnabled(). A couple of other references
to kExperimentalAppBanners were either missed, or were added since then.
This CL switches them over too.
