[4.4.14]: Purging pending users fails when pending users have Commerce orders

[peteeveleigh]

What happened?

Description

The Garbage Collection routine throes an Exception during the purge pending users phase if a pending user has an order.

Steps to reproduce

1. Create and complete an order for a user who hasn't activated their account
2. Ensure the purge pending users schedule will catch this account
3. Attempt to manually run garbage collection

Expected behavior

The garbage collection (pending user purge) should log the problem, skip that user, and continue to purge pending users

Actual behavior

The garbage collection (pending user purge) stops with an Exception. Thus no other pending users are purged.
