There are a few places in core that were preventing this from working by explicity setting `$wpdb->suppress_errors` to `false`. Instead, they should inherit the value that existed before errors were suppressed.
This allows Multisite unit tests to run without explosive database errors, and allows `$wpdb->suppress_errors` to be overridden all the way down the chain.
Fixes#26102.

wp-tests-config.php can/should reside in the root of a develop checkout. `phpunit` should be run from the root.
