Cleanup dream complication setting to reflect single toggle users see in
Settings.

The original implementation was designed to allow users to individually
enable/disable certain complications. However, we have since decided to
simplify the complication controls around a single master toggle. This
fixes an issue where when new complications are added, we will no longer
switch the toggle to off in Settings.
