Adding checkout step makes checkout stuck in this new step

[mbajur]

After defining a new checkout step, when user enters this step during checkout - he gets stuck in it and can't proceed.

Expected Behavior

After adding a new before: :address checkout step, user should be able to pass this step during checkout

Actual Behavior

After clicking "save and continue" on this new checkout step page, user get's redirected back to it instead of being redirected to address

Possible Fix

I managed to make it working in my instance by doing:

base.insert_checkout_step :additions, before: :address
base.add_transition from: :additions, to: :address
base.remove_transition from: :additions, to: :additions

So apparently doing only instert_checkout_step does not create a next transition from additions to address and also it creates a wrong next transition from additions to additions (and that's why it gets stuck i suppose)

Steps to Reproduce

1. Add insert_checkout_step :additions, before: :address to your order decorator
2. Go to checkout
3. Try to pass this new additions step
