Database checks using Great Expectations had not been run against the production database until the move to Postgres. @RickiJay-WMDE found a number of tests failed; please refer to the changes made in the pull request for expectations that had to be altered. Assess the changes, determine if any merit fixing data - such as removing trailing whitespace from wikibase names - or if the expectation didn't make sense in the first place - such as expecting ARTICLE_PATH values to be non-empty.

AC:

• Database checks pass
• GX checks make reasonable sense
