logistics.py and scraper.py need tests

[keeganskeate]

Unit tests need to be written for logistics.py and scraper.py in the cannlytics module. The tests should be named logistics_test.py and scraper_test.py and should be located in the tests directory. See firebase_test.py and find_labs_dev.py for examples of unit tests.

A way to test the functions can be to use them to find details for licensed cannabis waste disposal facilities in Oklahoma. Ideally, details can be found for a facility given only it's name, e.g. Egnite Waste Management. A map of facilities can be found at https://oklahoma.gov/omma/businesses/list-of-licensed-businesses/licensed-waste-disposal-facility.html
