Merge lp:~mvo/software-center/lp1005104 into lp:software-center

[Michael Vogt]

This fixes a regression introduced in r3006 that causes the initial click on a app to now show
up in the navigation history. The visible effect is that the back-button does not get sensitive
when clicking on a banner item or on a app in "whats new".
