Fix failing functional tests

These, to be specific: http://bamboo.s/browse/NX-DISTT-TLNX-403/

The problems were with the drilldown code, not the tests, so… yay!

I only have one question about a loadStore() override in the Users.js controller. Question inline below.
@adreghiciu This function was causing the functional tests to fail. The application seems to work fine without it, but I wanted to ping you first.

If this code is necessary, I can just add a call to me.callParent(arguments), which should solve the problem as well.
