fix: Remove erroring endpoint "/login/<provider>/<register>" from AuthOAut…

[dkalamar]

…hView

Description

Keyword argument register was removed from AuthOAuthView.login as part of #1707. However, the endpoint /login/<provider>/<register>/ is still exposed, resulting in a 500 error whenever it is called:

TypeError: AuthOAuthView.login() got an unexpected keyword argument 'register'

This PR fixes this error and any calls to that endpoint will properly return a 404 instead.
