style: restructured and renamed VisProg.test.tsx to VisProgStores.test.tsx

renamed as the functionality being tested is contained within the VisProgStores.tsx file and thus the filename for the tests should reflect that relation, so order is preserved in the project.
also added a second describe layer to group the tests for all FlowStore functions together for organisational purposes.
