[evolution/webkit: 69/171] Make EAttachmentButton unexpandable if no attachment PURI follows

    Make EAttachmentButton unexpandable if no attachment PURI follows
    
    When an expandable EAttachmentButton is inserted to EMailDisplay but
    (for any reason) we are unable to write/display widget of the attachment
    make the button unexpandable. Otherwise the EAttachmentButton wrapps any
    following widget (usually another EAttachmentButton) and everything goes crazy
