Fixed 4 congressmen whose 18 entries were incorrectly entered.

[rudeboybert]

Four congressmen (across 18 rows) with suffixes had two errors:

1. One too many comma in CSV row
2. lastname and suffix switched

They were:

• Pierre,Samuel, IV,du Pont,, changed to Pierre,Samuel,du Pont,IV,
• Harold,John, Jr.,,Daub,, changed to Harold,John, Daub, Jr.,
• Itimous,Thaddeus, Jr.,,Valentine,, changed to Itimous,Thaddeus,Valentine,Jr.,
• John,Alexander, III,McMillan,, changed to John,Alexander,McMillan,III,
