ActionController::InvalidAuthenticityToken in SubmittersController#create

[Janell-Huyck]

The app crashes upon creating new submitter after logging out and using back arrows to get to submitter creation page. Reproducible

Steps to recreate:

1. start the app at localhost:3000
2. create a submitter, hit submit
3. create a work
4. click "I'm finished"
5. use the back arrows to navigate back to the page where you created your submitter
6. notice that the form is pre-filled with your old information.
7. click "submit" on the submitter creation page where your old information shows
8. App crashes:

The same process and results happen with the admin login.

I suggest using begin/rescue blocks to gracefully handle this and redirect the user to a fresh login page.
