Fix for JCLOUDS-655

First time committing to jclouds, let me know if there are any style guidelines I missed with this change.
I can clean up almost all of this with autoformat, but the `ServerInternalWithoutImage()` layout is apparently special. If you look at the original version, there are two different styles of indentation. [One](https://github.com/jclouds/jclouds/blob/1.8.x/apis/openstack-nova/src/main/java/org/jclouds/openstack/nova/v2_0/config/NovaParserModule.java#L154) is like mine and the [other](https://github.com/jclouds/jclouds/blob/1.8.x/apis/openstack-nova/src/main/java/org/jclouds/openstack/nova/v2_0/config/NovaParserModule.java#L167) isn't. Seeing as autoformat matched one and not the other, I'm inclined to think that one indentation style wasn't intentional.

Do you know which one was intended? Or are you concerned more with isolating changes for this commit?
