feat: verbose fail messages on invalid invitation

Description

• the fail messages should now informatively and extensively cover the failure scenarios
• the redirect from the invitation is now presented after form completion
• sends also the group in the canInvitationBeAccepted check
• do not display needs to be verified tooltip if the email in the group application form is the same as the one from the invitation

How to test

• Pretty much same as !281 (merged). Set up an invitation and change it in DB to EXPIRED, REVOKED and ACCEPTED states. Each time you open the application with the invitation token you should be correctly informed about the wrong state of the invitation.
• Try different group than the one from invitation in the url.
• Try to use the email from the invitation in the form and see if needs to be verified tooltip disappears.
• Check that redirect after completion works as it should, when present in the invitaition.
