[balsa: 1/2] balsa-message: Restore text copy

[Peter Bloomfield <peterb src gnome org>]

commit eaeb917d725fa10fd90866e66d2fd766e2d1dde2
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Mon Aug 17 11:17:25 2020 -0400

    balsa-message: Restore text copy
    
    Edit:Copy has been broken for a while, because BalsaMimeWidgetText is
    now a container, not the actual text widget.
    
    * src/balsa-message.c (balsa_message_can_select):
      Check the mime-widget's text-widget, not the mime-widget itself.
