Fix update component selection shows wrong package sizes.

Task-number: QTIFW-302

During the update of KdTools we removed a bit to much code, so the
compressed/ uncompressed size was never passed to the component. Now
we keep and set it properly again. Force an update of the uncompressed
component size once we have calculated all checked components.
