re-contribute detail tabs with initialId on each selection

Both tickets and decisions extensions now uncontribute and
re-contribute the detail tab on every selection, passing the
selected ID via initialId. This guarantees the view loads
immediately — no first-click miss from the widget not being
built when the message fires.
