Remove legacy stuff from DndUtil

See original GitHub issue

A couple of things noticed in the DndUtil class:

public static final String DND_CONNECTOR_COMPATIBILITY = "frontend://dndConnector.js";
private static final String MOBILE_DND_POLYFILL_URL = "context://webjars/mobile-drag-drop/2.3.0-rc.1/index.min.js";
private static final String VAADIN_MOBILE_DND_POLYFILL_URL = "context://webjars/vaadin__vaadin-mobile-drag-drop/1.0.0/index.min.js";

Hi @Tonne-TM, thanks for the feedback, I just checked the source code, there is no more frontend://dndConnector.js in the source code. Have you tried to clean the project? delete node_modules, package.json, package-lock.json, target etc.

I think the original forum post could have been included here - as it had the context to the issue and logs about what might be going wrong. IIRC it said that something tried to load "frontend://dndConnector.js" and that a) should not happen and b) cannot work Flow 3 onwards.

The constant DND_CONNECTOR_COMPATIBILITY should be removed and not used at all as it is for ES5 browsers, that are not supported starting from v15. As Leif says, the mobile dnd polyfill is a different thing, and I don’t think it had anything to do with the error the user had.
