    Try to scan_ccache() after leash picks a cache
    
    We need to call scan_ccache() in order to notice that there
    are credentials and read their expire time.
    
    The call to scan_ccache() in the Leash case was inadvertently
    removed as part of commit 8651f3339ccc5a623172a8edfb9cf522883acacd.
