Incorrect module resolution

[slavchev]

As reported here

Steps to reproduce

tns create app1
cd app1
tns platform add android
npm install moment
[see the code fragment below]

var moment = require("moment");

moment.locale("fr");
console.log(moment.locale()); // "fr" expected
var m = moment();
m.locale("da");
console.log(m.locale()); // "da" expected

The first time moment module is resolved as

/data/data/<app package>/files/app/tns_modules/moment/./moment.js

And the second time moment module is resolved as

/data/data/<app package>/files/app/tns_modules/moment/moment.js

Should always use canonical paths.
