[EC-381] Transition settings service into providing observables (#3253)

* [EC-381] Deleted unused method clearCache from Settings Service

* [EC-381] Marked settings methods as obsolete on State service

* [EC-381] Using observables on settings service

* [EC-381] Added unit tests for Settings service

* [EC-381] Checking userId on clear

* [EC-381] Updated references to StateService activeAccountUnlocked$

* [EC-381] Updated getEquivalentDomains to return observable

* [EC-381] Updated settings service to user concatMap on activeAccountUnlocked$

* [EC-381] Renamed getEquivalentDomains to equivalentDomains

* [EC-381] Completing Behaviors on settings.service tests

* [EC-381] Removed unused settingsPrefix from settings service

* [EC-381] Removed equivalentDomains from settings service and added type AccountSettingsSettings

* [EC-381] Updated settings service settings$ to not be nullable

* [EC-381] Settings default to {}
