Depends on D119610. After fixing the error with targetList.destructor, calling CDP::stop() without having called CDP::start() before will trigger another failure.
This is because it will trigger a late load of RecommendedPreferences which will try to automatically initialize preferences
As we discussed about moving the init to be only performed during a call to applyPreferences, I am doing this change here to avoid the error.
This will not yet allow to call this from BiDi, or it would have to call it with an empty `preferences` map.
