Geometry parcel recalculating #381

Status quo

In case of errors on linked services, the parcel calculation might fail, leading to a never-ending spinner on the spatial reference box.

There should be some sort of recalculation being triggered somehow.

Improvement

Each time a client requests the parcels of a geometry using the GeomParcelsView, certain checks are done to differ between states like in-the-making or no-results. However, since the background process (in celery) can not be watched by the view class directly, we need to extent the Geometry model in a way, that we can directly see whether the process of calculating is still running.

If the process is "still running" but a certain time has passed, we can assume the process died in one or another way. In this case the GeomParcelsView shall trigger the calculation again.
