Updating response paths for orcid settings

This, along with
projecthydra-labs/orcid@7816a7668c21c724fd41e9631c322b5aab996057,
moves towards a better Orcid experience.

In particular this addresses the behavior when a user creates their
Orcid profile connection. Instead of giving a weird message, it
redirects to the orcid settings with a message that their request
has been submitted.
