Poland S7 (Kielce): Could not parse updates.csv line

[yakra]

Saw this while running some siteupdate tests:

[175.4] Reading updates file.  Could not parse updates.csv line: 2018-11-12;Poland;S7 (Kielce);Route extended at south end from exit 97 to Brzegi

The root column is missing from the updates entry.

replace with:
2018-11-12;Poland;S7 (Kielce);pol.s007kie;Route extended at south end from exit 97 to Brzegi
