Title: Fix back button

- Store params to session before each request
- Not ideal. I wanted to the model to save and load from a store (session in this case). This isn't possible due to logic in currency inputs and not being able to persist user inputs to session.
- We then load the model from the session
- Back buttons then are links to the previous step
