tokio-xmpp: @id wasn't correctly added to every stanza

Maxime “pep” Buquet created 2 years ago

This commit moves the code adding @id to AsyncClient and SimpleClient,
instead of on the lower level send_stanza helper, which seemed to only
be used internally.

Support is also added for Component.

This removes the addition of @id on elements like <auth/> or <bind/>,
which probably weren't required anyway?
