tenants:add add even if tenant already present making duplicates and malfunction of previous one.

tenants:add create new tenant even if tenant with same name and secret already present making duplicates and malfunction of previous one.

How to get:

1. create tenant docker exec -it scalelite-api ./bin/rake tenants:add[name, secret]
2. create meeting - everything is ok.
3. create same tenant again: docker exec -it scalelite-api ./bin/rake tenants:add[name, secret]
   new tenant with new id is added.
   here work unpredictable, moodle can get issues with api requests.
4. remove second tenant (duplicate): api returns wrong secret

fix:
rename first tenant:
create tenant docker exec -it scalelite-api ./bin/rake tenants:update[id,name2, secret]
rename first tenant to original name:
create tenant docker exec -it scalelite-api ./bin/rake tenants:update[id,name, secret]

Ran into this issue as well, albeit by accidentally renaming a tenant to another existing tenant's name with tenants:update. Your method of then fixing the other tenant worked, thanks.
