Tenant settings are not deleted in the REDIS database when you delete a Tenant.

[Tecumtha]

I have a problem with the Scalelite API.
In detail with the data in the Redis database.
It does not delete all entries correctly if you delete one or all tenants.

To Reproduce

When you add tenants and then add various settings to the tenant.

As an example: muteOnStart=true
Entries are created under “tenants_setting” for the settings in the REDIS database.

If you delete the tenants, not all information will be deleted and the "tenant_settings" will remain in the database

When you then set up tenants again, new entries are generated in "tenant_setting" and the information there is doubled.

Deployment:

1. Deployment: default systemd deployment and alternate docker-compose one
2. Versions: v1.5.1.7
