Core Rule Set tests: WordPress's recorded requests go through the shared check (closes #284)

WordPress's recorded requests now go through wantRecordedRequestsPass,
so a request with no body but a Content-Type is also inspected while
bodies are read, as every other app's is. The seven such requests,
wp-cron.php's, pass; wordpress.conf is unchanged.
