My system has Flask-Security 3.0.0 which contains a patch to Security.init_app

-        if not self.datastore:
-            self.datastore = datastore
-        datastore = self.datastore
+        self.app = app
+        self.datastore = datastore

https://github.com/mattupstate/flask-security/commit/3701b91d4d3e41036872a3f35db51e44e0681109

To get the old behavior we need to pass the datastore along again else
it gets overruled by the default None.
