test_list_servers_by_admin & test_list_servers_by_admin_with_specified_tenant: mismatch error when admin tenant's VM is already spawned

[Guillaume Chenuet]

I'm fencing a bug when i tried to execute these tests:
- tempest.api.compute.admin.test_servers.ServersAdminTestJSON.test_list_servers_by_admin
- tempest.api.compute.admin.test_servers.ServersAdminTestJSON.test_list_servers_by_admin_with_specified_tenant

If I try to execute these tests when a VM is already spawned by admin tenant, it's failed with this kind of error:

But if I try without VMs spawned by admin tenant or VMs spawned by an other tenant, it's works:

# source adminrc
# nova boot --flavor m1.tiny --image cirros-0.3.4-x86_64 --nic net-id=94e10ab3-65f4-4bb7-bc9c-be6d703b25a5 vm-admin
# testr run tempest.api.compute.admin.test_servers.ServersAdminTestJSON.test_list_servers_by_admin => FAILED
# nova delete vm-admin
# testr run tempest.api.compute.admin.test_servers.ServersAdminTestJSON.test_list_servers_by_admin => OK

More than a year no change, latest patch set is almost more than a year old. I assume this is not an issue anymore and I'm marking it as invalid. Feel free to reopen the bug by providing new information and set the bug status back to ''New''.
