remove eager callback execution in timer

bjmb · mambocab · commit 5e375cc9cdc0 · 2017-05-22T11:49:54.000-04:00
With our fix for PYTHON-755, you can now start timers with a negative
timeout in cluster.Cluster._start_timer. When this happens,
Timer.callback can be called twice, once in Timer.__init__ and once in
Timer.finish. The first is just an optimization, so we remove it here.
