feat(test): add componentSanityCheck helper for simple component sanity

 - simply runs the component through the instantiation and destroy lifecycle phases.
 - allows easy basic testing of component init/destroy for components that do not do much or have no behavioral spec yet.
 - when running on sauce this will become more valuable.
 - add sanity checks for some missing components.
