fix change how traffic light bulbs ids are giving using the gtgen environment unique id provider

• EntityRepository now passes their IUniqueIdProvider to the EntityProducer class
• EntityProducer now receives a IUniqueIdProvider and uses it to create a TrafficLightPropertiesProvider
• TrafficLightPropertiesProvider now as a shared pointer to the single IUniqueIdProvider of the simulation
• TrafficLightPropertiesProvider's function ToProperties is no longer static
• TrafficLightPropertiesProvider no longer controls ids with a function static int
• Tests have been updated
