environment: improve Object.toString for delegate objects

Browse Source 
If a JS object has an 'actor' property pointing to a ClutterActor,
include the actor's toString() output in the delegate's toString()
output. Eg:

  js>>> Main.panel
  [object Object delegate for 0xff6080 StBoxLayout.menu-bar "panel" ("Activities")]
