Account: Composition to handle User and its identities
We have a lot of things that act upon a user record and one or more of it's identities at the same time: * Sing up: Create a user and it's initial identity * Rename: Change the username and create a new identity, turn old into an alias * Cancel Account: Remove user and all their identities. In order to keep the User and Identity behaviour isolated but still have a this logic represented in a sinle place the Account model deals with all these things. We could have overwritten the User#create, User#update and User#destroy methods instead. But then we would always create identities, even if we only need a user (for example in tests).
