Tried to load angular more than once - Angularjs + Meteor:

I am getting this warning in my browser console:

Tried to load angular more than once.

Please check my repository for error which I reproduced.

Also can anyone help me how can I update my Angularjs to latest Angular 1 version? Because I think that I am using an outdated package of Angularjs
