/**
* This method adds listeners to the given router and store and syncs their state with eachother
*
* ### Why?
*
* Previously the IDE had a circular dependency between a singleton router and a singleton store.
* This causes some integration testing headaches...
*
* At the time, the most effecient way to break this ciruclar dependency was to:
*
* - Replace the router with a factory function that receives a store reference
* - Have the store write to a certain state that can be watched by the router
*
* Hence... This helper function...
