Update processImageForcedTask for new ApCorr behaivor

Since aperture corrections have been moved out of the base measurement
task, application of aperture corrections and the afterburner task
must be added to tasks which need these functionalities. Since the
forced measurement task has no default model flux, afterburners
are set to a NoOp by default.
