FIX: Click not opening query (#191)

Due to recent core changes for Ember in
0221855ba7
and 952b033165
the correct way of calling these actions must be observed,
otherwise clicking on a query did nothing.

This commit fixes the click and also makes scrollTop
work with the new {{on X}} Ember syntax.
