This PR follows up on #818. The check on the vacant synaptic elements is moved to the decay function of the synaptic elements to ensure that the deletion of elements still takes place correctly by the sp_manager.

I suggest @sanjayankur31 as reviewer for this.

@sanjayankur31 @sdiazpier After this change, Archiving_Node::get_synaptic_elements_vacant() may return a negative value. Is that sensible?

@heplesser - the way structural plasticity is implemented, ArchivingNode::get_synaptic_elements_vacant() < 0 implies that connections need to be deleted. It's used in SPManager::get_synaptic_elements(). (I hadn't realised this either which is why my earlier fix in #818 was incomplete).

I'll use the review tools. Sorry about that!
