function UpcastingTest::testUpcasting

Confirms that all parameters are converted as expected.

All of these requests end up being processed by a controller with the signature: f($user, $node, $foo) returning either values or labels like "user: Dries, node: First post, foo: bar"

The test shuffles the parameters around and checks if the right thing is happening.
