This sript refreshes all GET queries. Because of that some tests had to be modified. And api resposnes are reproducible now (sets results are changed to a "sorted" set, so with every query we should have the same response).
Second big change is that overlay iamages are stored differently (there are no overlays in submaps anymore)
