Schedules the currently set job (if any).

<p>This method can be called multiple times. It is guaranteed that each job set will be
executed no more than once. It is guaranteed that the last job set will be executed, unless the
job was cleared first.

<p>The job will be scheduled no sooner than <code>minimumJobIntervalMs</code> milliseconds
since the last job started.

@return true if the job was scheduled, false if there was no valid job to be scheduled
