Bugfix: avoid 500 when resending confirmation

The resource argument in the
`after_resending_confirmation_instructions_path_for` method is actuall a
symbol, not a user object. Avoiding calling methods on this argument
when redirecting to the almost_there path

part of:
https://gitlab.com/gitlab-org/gitlab/-/issues/333693#note_602683385
