    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
