Fixes a NullPointerException after import validation (#20151)

* Fixes a NullPointerException after import validation

If the import validation (when getting a user by email)
returns null, indicating that the user entity should be
removed from local storage, an email equality check results
in a NullPointerException.

This commit fixes this issue by explicitly checking for null.

Closes #20150
