    GeditDocument: make sure that metadata_info exists
    
    To fix this warning:
    CRITICAL **: set_gvfs_metadata: assertion 'G_IS_FILE_INFO (info)' failed
    
    The bug occurred when opening a non-existing file from the command line,
    and changing something (e.g. enable the spell checking) that sets a
    metadata.
    
    An empty GFileInfo is used to collect the metadata even if the file
    doesn't exist. So when the file is saved, the metadata isn't lost.
