* Make it possible to add a title for wiki tests.
* Added such a descriptive title for all the existing tests,
with a comment indicating what should be done with the test
* `(MOVE)` means the test will be moved closer to the
corresponding `IWikiSyntaxProvider` (similar to what was
done in r3122)
* `(FIXME)` means the test should be changed in order to use
a generic link resolver
