Fix Bill History Scraper

[ACoullard]

Summary

Fixes a bug where billHistory items with null dates ( some of which were present in bills from session 194 ) would fail to be ingested and possibly crash the entire scraper batch.
Addresses issue #2120

Steps to test/reproduce

Running the scrapers should no longer produce errors that look like the following:
