SQLite Compatibility #112

When I manually run the tests locally with SQLite, a lot of scenarios are failing. Not surprising given the custom db queries used in that command.

Some failures are also because of wp site empty. See wp-cli/entity-command#430 for a related issue tracking compatibility of that command.

In other instances there seem to be errors when performing the SQLite queries, erroring with integrity checks.

Let's investigate those issues and figure out the course of action.
