    tests: Test both JSON and XML cursors
    
    There is no exposed mechanism to decide what cursor format do
    an endpoint/cursor negotiate between themselves, as a result
    we are currently only testing the JSON cursor format.
    
    Add a test-only environment variable so that TrackerEndpointHttp
    prefers a given TrackerSerializerFormat, and run cursor tests
    twice to ensure we test all cursor paths on HTTP connections.
    
    This additionally also exercises the XML serializer on the HTTP
    endpoint side.
