core (xmpp): avoid starting several clients at the same time:
a check is done to avoid running startConnection several times at once, which would lead
to the creation of several SatXMPPEntity instances at the same time, resulting in many
issues.
If startConnection is called while a previous one is not finished yet, a CancelError is
now raised.
