QFileSystemWatcher does not signal directoryChanged() when files are
modified in a watched directory. QTBUG-8945 was closed with the
decision that it should not signal. Updating the docs and tests to
reflect this fact.
The test code that is being changed is a partial revert of Qt4 commit
1428cc6d71a65c1ac7123c9c4cc3cfaf225cceed. It appears that Symbian
supported directoryChanged() on modification, hence why the check
was for 0 or 1.
