Fix invite request input not being shown on sign-up error if left empty (#13089)

If the “Why do you want to join?” textarea is left empty and the entered params
do not validate, the textarea isn't shown again, unlike other fields.

This commit fixes that by populating an empty `UserInviteRequest` when needed.
