The previous initializer API was deprecated in Ember 2.1 (See
http://emberjs.com/deprecations/v2.x/), so this updates the initializer
signatures to accomodate that change.
Also, remove the registered deprecation from the workflow.
When I changed tabs-list-view to be a component I missed the fact that
config is not registered for components, which resulted in not showing
the running jobs tab at all. This commit fixes the situation.
