WPDB: Make sure we don't run sanity checks on DB dropins. 

Previously, we'd run the sanity checks if `is_mysql` was not set to `false`. This caused problems for DB drop-ins that didn't define `is_mysql` at all. Instead, we can just check if `is_mysql` is `empty()`.

Also fix some unit tests that accidently ran correctly because of the strict `false ===` comparison.

Fixes #33501.
