Pass empty dict not None for empty environment

The server rejects any request with a None environment, so pass an
empty dict not None (we should probably also make the server more
robust so it can cope with None, but this seems the quickest and
most backwards compatible fix for now)

Some functional tests for object versioning

Also fix some exception-handling stuff in functional tests; at some
point, ResponseError() started needing two more parameters, but the
functional tests (not swift_test_client, just tests.py) still had a
couple spots that were not passing in the new params. Now they're
optional again, and if you omit them, then the stringification of the
ResponseError is just a little less useful than it could be.
