Title: Xmpp service

XMPP requires a client to send its presence and to request its roster upon
login.

Smack can do this implicitly. The feature can be controlled with
`ConnectionConfiguration.setSendPresence(boolean)` and
`ConnectionConfiguration.setRosterLoadedAtLogin(boolean)`.
Both values default to `true`.

This commit removes superfluous calls.
