    [CalDAV/CardDAV] Append ending slash to URL when missing
    
    The URL set in the ESource is supposed to point to a collection
    and as such should end with a forward slash. While some servers
    do not care that much, some others can report an error when
    the ending slash is missing. This ensures it's always there.
