fix error on upgrade caused by new vendordata2 attributes (#869)

In #777, we added 'vendordata2' and 'vendordata2_raw' attributes to
the DataSource class, but didn't use the upgrade framework to deal
with an unpickle after upgrade. This commit adds the necessary
upgrade code.

Additionally, added a smaller-scope upgrade test to our integration
tests that will be run on every CI run so we catch these issues
immediately in the future.
