chore: upgrade to 4.0.0 stable

When I checked out the repo and ran yarn && yarn start it threw this error:

ERROR in Error encountered resolving symbol values statically. Calling function 'BrowserModule', function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol AppModule in /Users/mattlewis/Code/open-source/ng-universal-demo/src/app.ts, resolving symbol AppModule in /Users/mattlewis/Code/open-source/ng-universal-demo/src/app.ts

Upgrading to 4.0.0 final and adding the animations dependency seemed to solve it 😄

+1 on this! Was about to submit a PR before I saw this one :) Working great for me as well. Getting sub-10ms response times too ❤️

This worked perfectly for me.
