At line 103 of file app/app.js, there is a statement window.web3 = web3; with condition if (window.web3), comment out the condition line, then there would be always a defined web3.
I'm not sure whether this is the correct solution, it just works for me.

in app/app.js you add

if (typeof web3 !== 'undefined') {
web3 = new Web3(web3.currentProvider);
} else {
// set the provider you want from Web3.providers
web3 = new Web3(new Web3.providers.HttpProvider("http://"+GETH_HOSTNAME+":"+GETH_RPCPORT);
}

and delete var Web3 = require('web3');
