[Explorador] RouteStopPattern Visualizer stops working

[glaand]

Example URL of the problem: https://tpp.pt/explorador/#/route-stop-patterns?bbox=-8.778762817382812%2C41.05864414643029%2C-8.461189270019531%2C41.221018745822505&traversed_by=r-ez3f-801

When selecting the first 2 RouteStopPatterns, it works as it should, selecting and unselecting the RSP with the radio buttons, but as soon as the last one is selected and shown, it stops working and the console shows TypeError: this.store.peekRecord(...) is null whenver a radio button is pressed.

The function where the problem occurs is here https://github.com/tpportugal/tpp_explorador/blob/c9ee92966c7586d290e506a8de97aab1c65e31a0/app/route-stop-patterns/controller.js#L92
