Do not reset error occurrences for non-production releases

Since today, when a release is triggered for any non-production environment, the occurrences of errors are not reset anymore. Only when a release is triggered for a production environment are errors reset and notifications about re-occurring errors sent again.

This is a temporary change in behavior until Tideways can store, reset and notify about error occurrences for each environment individually.

See the documentation Deployment Events for more information.
