    search-view: only decrease search counter when something is removed
    
    Because we were blindlessly decreasing the search hit counter without
    considering that we could've not removed anything, the search hit
    counter is going nuts.
    
    Fix that by properly checking if something was removed, and only decrease
    the search hit counter when that happens.
