[TIMOB-9123] Mobileweb: require() with absolute path fails

Problem

Whenever an absolute path is used for a require in mobileweb, I get the red screen of death indicating that the module cannot be found.

Expected Behavior

Like with Android and iOS, when an absolute path is given for a require(), the call should be made relative to the Resources directory.

Test Case

The following test case work fine in Android and iOS, gives a red screen in mobileweb

app.js

require('/test/test');
var win = Ti.UI.createWindow({
    backgroundColor: '#fff',
    fullscreen: false,
    exitOnClose: true
});
win.open();

test/test.js

module.exports = {};
