    desktop: ensure desktop directory on application init
    
    Until now we were creating the desktop directory in a lazy way, like
    any other cached directory.
    
    However, we have the problem that at some point we have to dispatch
    between different types of files, when creating them for the cache.
    
    We cannot know when we will need to create the desktop directory for
    first time in order to discern between that type of directory, or the
    regular one.
    
    What we can do is ensure that we created the desktop directory before
    any other part of nautilus request it. In this way, we can create it
    on our subclasses of the desktop, and after that, nautilus will request
    the cache as a regular use, without the need to special case the
    desktop.
    
    For that, create the desktop directory when the desktop application
    starts, holding the reference so the cache doesn't release it, and then
    let nautilus work as expected.
    
    For that, in previous commits we moved the file dispatching to be inside
    the directory, so now any file creation happens inside the directory,
    and therefore we can control, when creating the desktop directory, what
    subclass will be called.
