Timo Tijhof 498ef943dd Allow custom teardown/setup per module through Qunit.newMwEnvironment
- Instead of having newMwEnvironment only create an object with
  setup() and teardown() that is passed to module() which uses them.

  Also allow a module test to pass additional setup/teardown to run.
  Otherwise one would have to extend newMwEnvironment, this is
  simpler.

- Also added a few unit tests of the test runner's newMwEnvironment
  method itself. (also serves as document/example for how to use it)

- This changes the signature of QUnit.newMwEnvironment. Was only
  used in 2 places in core. Adding release notes just in case.

- Needed to fix a unit test breakage in mw.Uri
