[gotr] handle_incoming_msg: set XHTML correctly
In case we get XHTML in OTR message for some reason (e.g. from gajim 0.16.4), we will see that instead of decrypted content, if we don't delete existing html first. This doesn't touch old code in handle_outgoing_msg (which will get exectued gajim<0.16.4). That should work between versions, given handle_incoming_msg will overwrite any XHTML in OTR-encrypted message.
