Fix `scene.updateConfig()` memory leak #697

Closed bcamper closed 5 years ago

bcamper commented 5 years ago

Fix memory leak when scene.updateConfig() is called, due to dangling style references in WorkerBroker (outdated style worker broker targets were not removed when new styles were built).

See discussion in https://github.com/tangrams/tangram/issues/696. Thanks to @rihteri!
