We were calling twice showPage() with the correct page, here and in show() / zoomFromOverview given that _resetShowAppsbutton was called from the signal 'showing' of overview. Given that the call to _resetShowAppsbutton is only actually used when hiding the overview we can actually put the checked state of the button to false when animating from overview so it shows the workspace page, causing the same behavior of _resetShowAppsbutton without all the shenanigans of resetting when the hiding overview signal is triggered. https://bugzilla.gnome.org/show_bug.cgi?id=732901
