[geary/wip/765516-gtk-widget-conversation-viewer: 94/112] Fix in-window and in-comversation composers not getting cleaned up.

[Michael Gratton <mjog src gnome org>]

    Fix in-window and in-comversation composers not getting cleaned up.
    
    Calling destroy ensures the composer widget cleans up after itself, maybe
    because of the signal handlers added in ConversationViewer::do_compose
    and ConversationListBox::add_embedded_composer?
