    shell: Fix resetting page selection
    
    When the page selection happens when another page selection hasn't
    started yet, we need to cancel the previous animation, or only one
    of them might be effectively acted upon.
    
    This fixes the page from being selected if the search term is changed
    quickly (you'd end up at the overview page instead of staying on the
    search results page).
    
    Requires the clutter patch from:
