UI querying for simulation(s) status even when simulation(s) finished

When viewing simulation results (either via https://cardiac.nottingham.ac.uk/ActionPotentialPortal/simulations, or individual simulations via `https://cardiac.nottingham.ac.uk/ActionPotentialPortal/simulations/<sim id>/result`), the UI continues to query the `/ActionPotentialPortal/simulations/status/false/<sim id>(/<sim id>/<sim id>` etc) endpoint unnecessarily.
