Doesn't send initial presence to yourself

[Zash]

Vines doesn't send you your initial presence, which you MUST according to Section 4.2.2 of XMPP IM:

The user's server MUST also broadcast initial presence from the
user's newly available resource to all of the user's available
resources, including the resource that generated the presence
notification in the first place (i.e., an entity is implicitly
subscribed to its own presence).

Based on a quick look at lib/vines/stanza/presence.rb I would guess that switching the order of presence broadcasting and stream.available! should fix this.
