Treat the /[instcode]/home route like the /express?inst=[instcode] route.
If I am not logged in:
- https://gs-staging.galileo.usg.edu/express?link=afrk-asc1&inst=asc1 takes me to the Agnes Scott IdP via OA.
but
- https://gs-staging.galileo.usg.edu/asc1/home takes me to https://gs-staging.galileo.usg.edu/welcome?inst=asc1 with "Password for Agnes Scott College" in the "Know the Password?" box.
I think https://gs-staging.galileo.usg.edu/asc1/home should take me to the Agnes Scott IdP via OA to log me in to GALILEO.
