mix passport.setup not working

[wnederhof]

When running $ mix passport.setup after adding the dependency and running mix do deps.get, compile

I get:

** (UndefinedFunctionError) function Mix.Tasks.Phx.Gen.Html.build/1 is undefined or private
    Mix.Tasks.Phx.Gen.Html.build(["Account", "User", "users"])
    lib/mix/tasks/passport.setup.ex:23: Mix.Tasks.Passport.Setup.generate_account/1
    lib/mix/tasks/passport.setup.ex:13: Mix.Tasks.Passport.Setup.run/1
    (mix) lib/mix/task.ex:301: Mix.Task.run_task/3
    (mix) lib/mix/cli.ex:75: Mix.CLI.run_task/2

mix phx.gen.html works as expected. I am running phoenix 1.3.0.
