unable to update dependacies

[x] bug report

Current behavior
When run npm update I am getting

Vladislavs-MacBook-Pro:udoma personal$ npm upgrade
@ng-seed/universal@0.4.0-beta.2 /Users/personal/code/udoma

Expected/desired behavior
Npm update successful

Minimal reproduction of the problem with instructions

1. Clone repo
2. Run npm update

What is the motivation / use case for changing the behavior?
So I can use the repo with the latest versions of node modules, install other node modules

Please tell us about your environment:
OSX

Node (for AoT issues): node --version = v6.10.3

@vlados actually npm updates the deps, but displays a warning if there're any unmet peer dependencies. So, things should work fine (because higher versions of those deps are already included in node_modules directory).
