Fabien "egg" O'Carroll 0a3e36cd62 Ensured uniqueness of slug in collections
We require that slugs are unique as slugs can/are used for routing purposes and
act as an identifier for a resource. As this is a core business rule, we want
to encode it in the entity so that it can be unit tested, and be enforced
regardless of underlying persistence layer
