Issue Description

When the username field is included in the protectedFields configuration for the _User class, the email verification link generated results in an "Invalid Verification Link" error. This seems to be caused by the username parameter being set to undefined in the verification link.

Steps to reproduce

Add username to the protectedFields for the _User class in the Parse Server configuration. Register a new user and trigger the email verification process. Check the email verification link sent to the user's email. The username parameter in the link will be undefined. Attempt to verify the email using the link, resulting in an "Invalid Verification Link" error.

Actual Outcome

The username parameter is set to undefined in the verification link, causing an "Invalid Verification Link" error when attempting to verify the email.

Expected Outcome

The username should be correctly included in the email verification link, and the link should allow successful email verification.
