Bug 62856 Add test to verify bug on MW 1.23 / ContentHandler usage

The test is SMW independent and relies solely on MW provided functionality to verify that the `ContentHandler` has an issue with `#REDIRECT` and `InternalParseBeforeLinks` on MW 1.23/MW1.24 while passing on MW 1.21/MW 1.22.

In comparison, the test passes for both `Parser` & `ContentHandler` on all MW versions when using a "normal" text (e.g '[[Lorem ipsum]] dolor sit amet ...').
