Issue 84 - Setting focus to first result to close on screen keyboards

Fix for #84, focus set to first result after initially searching to close on screen keyboard.

Change is basically removing the if statement, was there a reason not to change focus for first set of results?

Also added a test using document.activeElement instead of :is(':focus') as per: http://stackoverflow.com/questions/18850219/testing-for-focus-an-angularjs-directive
