No hook for db:seed

[atz]

We can copy migrations during the callback to MyApp::InstallGenerator, but we don't have a hook to make use of db:seed to populate the schema with initial values. We cannot run them in the InstallGenerator because without running db:migrate first, which is already otherwise being called by EngineCart after the generator.

What's the best move? Call migrate explicitly and end up calling migrate twice?

Running db:migrate twice sounds like a fine workaround.
