integration/container: fix flaky TestResizeWhenContainerNotStarted

This test was failing frequently on Windows, where the test was waiting
for the container to exit before continuing;

    === FAIL: github.com/docker/docker/integration/container TestResizeWhenContainerNotStarted (18.69s)
    resize_test.go:58: timeout hit after 10s: waiting for container to be one of (exited), currently running

It looks like this test is merely validating that a container in any non-
running state should produce an error, so there's no need to run a container
(waiting for it to stop), and just "creating" a container (which would be
in `created` state) should work for this purpose.

Looking at 8f800c941570ffcd087c920c37d3a368a5a19e6d, I see `createSimpleContainer`
and `runSimpleContainer` utilities were added, so I'm even wondering if the
original intent was to use `createSimpleContainer` for  this test.

While updating, also check if we get the expected error-type, instead of
only checking for the error-message.
