Missing "InvalidEmailException" for "resendConfirmationForEmail"

First of all, thank you for your wonderful work and the great library.

I have two suggestions which I will handle in two requests.

1.) Missing "InvalidEmailException" for "resendConfirmationForEmail":
For consistency reasons the method "resendConfirmationForEmail" should check the validity of the email as the other methods that deal with emails do.

Locate the resendConfirmationForEmail method and compare its email validation with the other email-related methods. Check how InvalidEmailException is raised elsewhere, then verify that invalid email input to resendConfirmationForEmail produces the same exception while valid input keeps its existing behavior.
