In summary, since !8028, trailing slashes have been removed from the OIDC issuer locations specified by Forgejo everywhere except in WebFinger responses at `/.well-known/webfinger`, which still includes a trailing slash and so no longer matches the issuer as specified elsewhere (such as at `/.well-known/openid-configuration`).

- Use mock helper functions, instead of home-brew solutions.
- Disable cron jobs that are not important to be run during integration tests and might even interfere.
- Avoid sleeping unnecessary, if there's some requirement then sleep or retry until that requirement is met.
- Avoid trying to deliver webhooks that will always result in a failure.
