/**
 * This server simulates the behavior of /account/login on the Firefox Accounts
 * auth server in the case where the user is trying to sign in with an email
 * with the wrong capitalization.
 *
 * https://github.com/mozilla/fxa-auth-server/blob/master/docs/api.md#post-v1accountlogin
 *
 * The expected behavior is that on the first attempt, with the wrong email,
 * the server will respond with a 400 and the canonical email capitalization
 * that the client should use.  The client then has one chance to sign in with
 * this different capitalization.
 *
 * In this test, the user with the account id "Greta.Garbo@gmail.COM" initially
 * tries to sign in as "greta.garbo@gmail.com".
 *
 * On success, the client is responsible for updating its sign-in user state
 * and recording the proper email capitalization.
