resize should not require network of the instance has a project_id

[Jian Wen]

How to reproduce:
  Boot then resize:
   image_uuid=`glance image-list | grep "cirros-0.3.0-x86_64-uec " | awk '{print $2}'`
   instance_name=vm_$RANDOM

   id=`nova boot --flavor=1 --image=$image_uuid $instance_name | grep ' id ' | awk '{print $4}'`
   sleep 20
   nova resize $id 2

On the instance's host raises:
2012-11-06 00:15:45 ERROR nova.compute.manager [req-eb41f288-8667-4f3e-be45-6f0a8ca75ad8 demo demo] [instance: b268463c-dad8-48d7-bda7-4b66a0a9fee9] Network 1 could not be found.. Setting instance vm_state to ERROR

Jian: FYI you can skip your crazy grep by just passing in --image=cirros-0.3.0-x86_64-uec
