audit failures with Rails 5.2.2
The following two failures can be seen, starting with https://github.com/rails/rails/commit/7794d00c7a966a63d98331cfd986edb1d2ccdb2c
AuditAssociationsTest#test_0002_Should audit associations on update [.../test/models/concerns/audit_associations_test.rb:27]: Expected: [, ] Actual: [, ] UserTest::audit user roles#test_0001_should audit when a role is assigned to a user [.../test/models/user_test.rb:1214]: Expected  to be empty.
Fixes #25602 - Correct tests for user role audits
Auditing user role changes should show the default role in the previous
version. Due to a bug in Rails 5.2.1 which is fixed in 5.2.2, this was
not showing up when the object was saved without reloading. We now
reload explicitly to allow backward compatibility for both Rails
versions, the reload can be removed once we upgrade to newer Rails.
