plugin XEP-0384: temporarily disable <iq> stanza encryption:

`<iq>` stanza encryption is implemented, but the `send` trigger doesn't catch all `iq`
stanza send (which are often sent directly with `xmlstream.send`), and some stanza
encryption may cause trouble (happened with disco on a bare jid).

It is temporarily disabled but should be reactivated before `0.9` release.
