Log Message:
-----------
Fix for [#25879] Particle Duplication issue with Linked in Objects from Groups.
* Only the first object (in scene object order) that instanced a dupligroup was rendered properly, because particle instances were checked for only after creating the render object (and even this check was done wrong).
* Now the actual render object is created only after both object and particle instances have been checked.
