post_user_delete error when deleting admin user from yunohost

[obrenckle]

Describe the bug

After upgrading from yunohost 11.0 to 11.1, I deleted the "admin" user from Yunohost, but got an error for the FreshRSS post_user_delet_hook.
It didn't block the user suppression process.
As far as I remember, admin wasn't allowed to use FreshRSS or among the FreshRSS users at all (not in the all_users group and no specific authorization).
Might be related to #124 ?

Context

• Hardware: Other ARM board, A20-OLinuXino-Lime2
• YunoHost version: 11.1.14
• I have access to my server: everything
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: Yunohost installed over a fresh armbian
• Using, or trying to install package version/branch: 1.20.2~ynh1

Steps to reproduce

• Delete admin user from Yunohost after upgrading from yunohost 11.0 to 11.1
• (non blocking) error in log:
  • FreshRSS error: username not found “admin”
  • Échec de l'exécution du script : /etc/yunohost/hooks.d/post_user_delete/50-freshrss

Expected behavior

No error.
