odd use of feature flags

in distroseries.py, for the new differences stuff

    def initialize(self):
        """Redirect to the derived series if the feature is not enabled."""
        def in_scope(value):
            return True

        feature_controller = FeatureController(in_scope)
        if feature_controller.getFlag('soyuz.derived-series-ui.enabled') != 'on':
            self.request.response.redirect(canonical_url(self.context))
            return
        super(DistroSeriesLocalDifferences, self).initialize()

This is buggy - it will match too many scopes, and its also way more code than is needed.

This is better:

    def initialize(self):
        """Redirect to the derived series if the feature is not enabled."""
       if features.getFeatureFlag('oyuz.derived-series-ui.enabled'):
           self.request.response.redirect(canonical_url(self.context))
           return
      super(DistroSeriesLocalDifferences, self).initialize()
