updated seed file to actually add tenants to users

removed the uniqueness from loan and loan_request
because it was silly

added a migration to remove user_id from tenants

Added bangs to the creates that didn’t have them
so that we’ll know when shit hits the fan

changed the tenant create to have two names because
a singular named store was blowing up every now and
then

Added a save because apparently it’s necessary

changed the random number to be higher
