old users are missing from smbpasswd

[Hemi03]

Describe the bug

Samba uses its own password hash, so every user has to be added using smbpasswd.
This only happens automatically for users that are created after the installation of the samba app.
The problem is that existing users are not added during install, but only new users threw the post_install hook.

Context

• Yunohost 11.2.10.3 (stable)
• samba app 4.13.13~ynh2

Steps to reproduce

1. add a user to yunohost
2. install the samba app
3. crate a new user
4. show all users in samba password store sudo pdbedit -L -v

Expected behavior

If a user installs the Samba app, they would expect every user to be able to access the samba /share.

Manual workaround

log into your ssh and run

sudo smbpasswd -a user_name

give the same password as the user has in yunohost.
