Project creation: Client allows invalid task geometry

[hauke96]

The server-log shows such occurrence, that invalid task geometries have been sent to the server. In an ideal situation the client would convert geometries or show an error. This doesn't happen here.

There should be a better handling of such invalid geometries in the client.

This was one of the geometry (a MultiPolygon) added:
