Nyall Dawson b637c7fe22 Prevent background execution of zonal stats
This algorithm is NEVER safe to run in the background, because
it directly modifies a layer in place.

We should:
- make a variant of this algorithm which returns a new layer
AND
- refactor the QgsZonalStats code to create a separate map
of feature->stats, and then modify the existing Zonal Stats
algorithm to apply these changes in a post processing step
