Title: Bugfixing focus on tab change

As said in issue #28 and [here on discourse](http://discuss.atom.io/t/focus-to-the-editor-when-changing-tab-by-clicking-on-it/3793), when clicking on a tab, the focus doesn't pass to the content of the tab.

After some investigations, it appears to be a missing return value for an handler.
