Some bug with columns #4260

When the columns are clearly indicated (using -C), they are only the result of --colums. Names of existing columns are not displayed. (Image 1, run using sqlmap.py -u ************ -p ************ --drop-set-cookie --threads=30 -o --retries=5000 --risk=3 --level=5 --random-agent --technique=BEUSTQ --beep -D ************ -T ************ --columns -C wrong_column1,wrong_column2)

This happens even if you specify a non-existent table through -T. (Image 2, run using sqlmap.py -u ************ -p ************ --drop-set-cookie --threads=30 -o --retries=5000 --risk=3 --level=5 --random-agent --technique=BEUSTQ --beep -D ************ -T wrong_table --columns -C wrong_column1,wrong_column2)

If you start a dump in an existing table of nonexistent columns, the program will try to dump. (Image 3, run using sqlmap.py -u ************ -p ************ --drop-set-cookie --threads=30 -o --retries=5000 --risk=3 --level=5 --random-agent --technique=BEUSTQ --beep -D ************ -T ************ --columns -C wrong_column1,wrong_column2 --dump)
