"cannot convert udefined or null to object" on initialisation with angular 4.0.0-rc.5 #14

Hi,

I feel the source of this problem is in ngrx but I'm not 100% sure, at least it manifests itself with it…

Basically, since I updated my application from angular 4.0.0-rc.3 to 4.0.0-rc.5 (see https://gitlab.com/linagora/petals-cockpit/commit/d7caeefe44262442e33dd024682282037ba02982 for the exact changes), I can run ng serve and then when I open the application with Chromium, I get the following error in the console:

Sorry, it should have been in ngrx/store, and it is actually already issued there: ngrx/store#357
