Self-hosted instance not emailing delete password to participant

[sunbladehub]

Due to the issues observed in #173, I deployed a self-hosted instance of gathio and configured my own SMTP service. Now emails are successfully sent to the event creator and to participants when the event details change.

However, the participants do not receive an email with the delete password, despite being informed that they will receive it upon registration. Do you know what could be the reason for this?
