LASD scraper doesn't extract

[ssciolist]

The issue in this scraper begins in the restruct_raw function, when many warning are thrown for not finding expected text. However, the function runs and returns restructured data. extract_from_raw() doesn't return extracted data because no death data was extracted so when line 241 runs, a comparison between nil and an int doesn't work. Fix the restruct function and the scraper should work in my opinion. Stack trace excerpted below.
