Fix trovestack clean to remove nova instances

If you run 'trovestack clean' any nova instances are not deleted. This
seems to be caused by the fact that the OS_PROJECT_NAME env variable
does not override the value found in the clouds.yaml file.

This was fixed by having the value passed in as --os-cloud change
based on the project name being cleaned.
