Separate the create and start phases in SchedulerSingleThreadTaskRunnerManager.

With this CL, single-thread TaskRunners created from a newly
instantiated SchedulerSingleThreadTaskRunnerManager aren't backed
by a thread (and hence their tasks can't run right away). Thread
creation is delayed until
SchedulerSingleThreadTaskRunnerManager::Start().
