Refactor: handle logo and shibboleth w/ helpers

This refactor is meant to serve as a small step in simplifying  `OrgsController#admin_update` controller action, which currently contains a lot of rubocop offences.

- Moved `attrs[:logo]` handling logic into `handle_logo(attrs)`

- Moved Shibboleth identifier handling into `handle_shibboleth_identifier(attrs)`
