In the scheduleTask method of Scheduler class, expression forceExternalLocation
is useless, since it always evaluates to false:
!image-2019-04-29-11-16-13-492.png!
So it can be removed. Moreover, by removing this expression, the code structure
can be made much simpler, because there are some branches relying this
expression, which can also be removed.
