nova instance-action fails if project_id=NULL

Bug description:
nova instance-action fails if project_id=NULL
Starting in api version 2.62 "an obfuscated hashed host id is returned"
To generate the host_id it uses utils.generate_hostid() that uses (in this case) the project_id and the host of the action.
However, we can have actions without a user_id/project_id defined.
For example, when something happens outside nova API (user shutdown the VM inside the guest OS).
In this case we have an action "stop", without a user_id/project_id.
When running 2.62 it fails when performing:
nova instance-action <instance_uuid> <req_uuid>
no issues if using:
--os-compute-api-version 2.60
===
The trace in nova-api logs:
