Illumination Correction task with overwrite_input=False is missing ROI tables

[jluethi]

We need to add copying tables over from the non-corrected image, otherwise the new image will miss the ROI tables.

My default would be to copy over all tables for now. We could be selective, but that gets complex when users add their own table types (e.g. condition tables) etc.
In most cases, users should not have feature tables when they run illumination correction. If they do, the correct behavior is not fully defined (one could argue either way)
