    downloads-manager: Fix crash when download fails
    
    It's wrong to acquire the session inhibitor when destination is created,
    because the download could fail before that point, causing the
    inhibitotr to be released before it has been acquired and triggering our
    assertions to ensure this does not happen.
    
    Instead, acquire the inhibitor immediately when creating the download.
