Subject: Fix message stanza with body changing MUC subject (#1569)

- fixes https://github.com/dino/dino/issues/1542
            - more consistent with
              https://xmpp.org/extensions/xep-0045.html#enter-subject:
                    "Note: In accordance with the core definition of XML stanzas,
                    any message can contain a <subject/> element; only a message that
                    contains a <subject/> but no <body/> element shall be considered a
                    subject change for MUC purposes."
