docker-py: skip broken ImageCollectionTest::test_pull_multiple

The ImageCollectionTest.test_pull_multiple test performs a `docker pull` without
a `:tag` specified) to pull all tags of the given repository (image).

After pulling the image, the image(s) pulled are checked to verify if the list
of images contains the `:latest` tag.

However, the test assumes that all tags of the image are tags for the same
version of the image (same digest), and thus a *single* image is returned, which
is not always the case.

Currently, the `hello-world:latest` and `hello-world:linux` tags point to a
different digest, therefore the `client.images.pull()` returns multiple images:
one image for digest, making the test fail:

    =================================== FAILURES ===================================
    ____________________ ImageCollectionTest.test_pull_multiple ____________________
    tests/integration/models_images_test.py:90: in test_pull_multiple
        assert len(images) == 1
    E   AssertionError: assert 2 == 1
    E    +  where 2 = len([<Image: 'hello-world:linux'>, <Image: 'hello-world:latest'>])

This patch temporarily skips the broken test until it is fixed upstream.
