> A simple script that reads a CSV file and writes it to an output file just renames the input file to the output file. 
> This optimization should not be applied to input files but only to temporary scratch files.
> Judging from quick local checks, this bug does not seem to affect data_type='frame' inputs, but only data_type='matrix'. Test script is attached.
> Tested on current master git branch (ef8b551103085b73d0b471db9df6c5c0748f7d94) on the file
