Subject: [PATCH] TpConnectionManager: retry introspection after CM exits, up
to once
Many connection managers automatically exit after 5 seconds of
inactivity. If the CM has no .manager file *and* exits in this way
while we are introspecting it, we would previously consider it to have
failed introspection - but with sufficiently unfortunate timing,
that can result in empathy-accounts not considering Haze to exist.
To avoid this, without going into an infinite loop if the CM fails to
introspect, retry once, but only once.
