[PFUser currentUser].email returns nil

Issue Description

Since upgrading to parse-server 9.9.0 (from 9.6.1) a call to [PFUser currentUser].email returns nil. This seems like a breaking change, since the _User table still has a valid email entry.

Steps to reproduce

Run Parse Server 9.9.0, and an iOS app with a valid user account. Once signed in try and access the .email object for the [PFUser currentUser] object and also the .username object.

Actual Outcome

Since upgrading just the Parse Server to 9.9.0 from 9.6.1, (and making no changes to the iOS code), [PFUser currentUser].email returns nil.

Expected Outcome

[PFUser currentUser].email should return the entry in the database.

Environment

iOS 18.7
parse_sdk_ios_osx : 6.1.1
bolts-objc : 1.10.0

Logs

n/a

Start by reproducing the issue with Parse Server 9.9.0, the iOS SDK, and MongoDB, then compare the result with Parse Server 9.6.1. Trace how the current user is returned and how its email and username fields are exposed; done means both fields match the valid _User database entries after the upgrade.
