TVB-2771: Clear SessionStoredSim on project delete (and not only)
Created by: VinczeRobert
I made some tests and deleting only the session stored simulator won't work, the burst config and the last_loaded_url should be removed as well + is_simulationloaded must be False in case you loaded a simulation and then you switched the project.
Is this okay in ProjectController or would it be better in SimulationController?
