Authentication failure when using direct return value from create_vsphere_client

[nikstuckenbrock]

Describe the bug

Calling the synchronous vcenter api leads to different behaviors depending on if you assign the return value of create_vsphere_client before usage.

Calling it directly from the return value raises this excpetion:

LocalizableMessage(id='com.vmware.vapi.endpoint.method.authentication.required', default_message='Authentication required.', args=[], params=None, localized=None)], data : None, error_type : UNAUTHENTICATED} 

Reproduction steps

Failure

x = create_vsphere_client(
    server="",
    username="",
    password="",
    session="",
).vcenter.vm.list()

Works

x = create_vsphere_client(
    server="",
    username="",
    password="",
    session="",
)
x.vcenter.vm.list()

Expected behavior

Both version work without errors.
