[Resolves #86] error running db seed task

• ensure listed tenants are created before trying to migrate them or seed them

Without being able to replicate the actual reported bug, this is the best i can do at the moment. I'll close the associated issue as well. If this is still a problem, then we'll need to investigate further how to find out the source of the problem

Hey! I was testing with the development branch, and I found that I wasn't able to migrate the tenants anymore. I narrowed it down to this PR. Here is the relevant result of running rails db:migrate with the development branch. It fails at trying to create the first schema (because it exists), and then the transaction is in an aborted state and nothing else can be done:

I think Apartment::Tenant.create should probably handle the case that the tenant already exists. Or maybe a conditional method like Apartment::Tenant.create_if_not_exists?

Also not trying to bother, but just wondering, when will this be released? is there a schedule or something? jut wanted to be aware of the time frame. I know this is time you give from your own, so not pushing or anything like that.
