Initial Deployment does not add nodes to ELB

Given clouds.rb has load_balancer properly defined
And you deploy a cloud with 'cloud start'
When the Elastic Load Balancer is created
And the nodes are started
Then once the deployment is complete, poolparty does not add the new nodes to the ELB defined in load_balancer block.

**when `cloud start` is run a second time, then the nodes are added to ELB successfully.
