Fix up StringIO use in tests for py3

Some spots in this file were already referencing six.StringIO, but
some were still using StringIO.StringIO, which does not work on
py3. This patch just makes them all use six.StringIO and removes the
now-unused (and wrong, on py3) import.

Remove test_create_port_with_no_ip

The check test_create_port_with_no_ip does can be performed by adding
self.assertEqual(port['fixed_ips'], []) to test_show_port.

Plus, amended docstrings.
