Fix strict_validation error

[feydan]

When I try to run pupa update sacramento, I get the following error:

File "/home/pupa/.local/lib/python3.7/site-packages/pupa/cli/commands/update.py", line 172, in do_scrape
  fastmode=args.fastmode)
File "/home/pupa/.local/lib/python3.7/site-packages/legistar/base.py", line 261, in __init__
  super(LegistarAPIScraper, self).__init__(*args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'strict_validation'

It appears we need to modify either the Pupa or the Legistar project to work properly together. This should allow us to eventually complete the run of the scraper to input the data into the database.
