[BUGFIX] Allow to resend the confirmation email from Registration and ResendConfirmationMail plugin

Resending a confirmation email can either be triggered by using a dedicated
`ResendConfirmationMail` plugin on a separate page or by manually linking to
the `resendConfirmationDialogue` action in a template of the `Registration` plugin.
The second option allows to use that action without having to add a page for it.
[[BUGFIX] Failing resend frontend view](a141aa5)
changed the code to only allow `ResendConfirmationMail`, but both options are valid.
