Fix blank error page when performing search with invalid regex.

Fix searches like this: https://danbooru.donmai.us/artist_urls?search[url_not_regex]=https://www/.artstation/.com/[a-zA-Z0-9-.] returning a HTTP 500 error with a blank page. Here the problem is that Postgres raises an error because `[a-zA-Z0-9-.]` is an invalid character class (it should be `[a-ZA-Z0-9.-]`). This error happens on the error page itself, when rendering the <link rel="next"> / <link rel="prev"> links in the <head>, so it causes the error page to fail.
