conn.image.images() gets 404 on subsequent pages

[Daniel Speichert]

The standard demo snippet for listing images:

    print("List Images:")

    for image in conn.image.images():
        print(image)

is failing when Glance has more than one page to report.

What seems to happen is in here: https://github.com/openstack/python-openstacksdk/blob/0.11.3/openstack/resource.py#L892-L899

the first time, the `uri` variable is `/images` and the `session` (~keystoneauth1.adapter.Adapter) is prepending /v2.

For the second page, the `_get_next_link` function is returning new uri such as:
 `/v2/images?marker=e182ceb2-c752-430c-9ac1-a1cab2e5e0bd`

This results in openstacksdk trying to GET /v2/v2/images?marker=e182ceb2-c752-430c-9ac1-a1cab2e5e0bd
which obviously results in 404.

It could be a bug in keystoneauth1 but probably a workaround in openstacksdk is needed.

Confirmed using 0.12.0, too, against a Pike deployment of Glance.
