chore: upgrade to ngrx v4

[maxime1992]

There are compatibility issues with ngrx v4 and AOT.

While those 2 are not playing well together, this PR should be on hold.

Your enableBatching meta-reducer needs to be wrapped in an exported function for AOT

// ------------------------------------------------------------------------------
export function batcher(reducer) {
  return enableBatching(reducer);
}
// if environment is != from production
// use storeFreeze to avoid state mutation
const metaReducersDev = [storeFreeze, batcher];

// enableBatching allows us to dispatch multiple actions
// without letting the subscribers being warned between the actions
// only at the end : https://github.com/tshelburne/redux-batched-actions
// can be very handy when normalizing HTTP response
const metaReducersProd = [batcher];

export const metaReducers = environment.production
  ? metaReducersProd
  : metaReducersDev;
