    documents: Don't open docs without a recommended app
    
    When a document type doesn't have a recommended application (or no
    external application at all), don't try to force open it.
    
    This prevents selected but unhandled files from being opened if one
    of the selected files can be opened (eg. one ePub + one PDF should only
    open the PDF file, and ePub shouldn't get opened in file-roller).
