Fix FreeU crash in ConsiStory script

Enabling FreeU called len() on the checkbox bool instead of the parsed
preset list, raising TypeError and aborting the run. Even without the
crash, all four FreeU parameters were passed the same value. Use the
parsed freeu_preset values, and log the invalid input before clearing it.
