Role Assignment Incorrectly Reports Inheritance when --name is Used

When retrieving role assignments via the openstack client, passing the --name flag will cause Keystone to not return the value of inherited, so openstack client always reports false.

My test environment is an OSA AIO using OSA 13.1.3, which is using Keystone commit 87d67946e75db2ec2a6af72447211ca1ee291940.

Steps to reproduce:
* assign a role to a user on a domain and pass --inherited, so the role will be inherited to the domain's projects
* run "openstack role assignment list --user <user> --name"

Example output with debug request response without --name:

:~# openstack --debug role assignment list --user 14bc7c6869374b33bd5125f6c61d44b9
