Allow warning: redefining 'object_id' may cause serious problems in the TransactionCallbacksTest

This commit allows the `warning: redefining 'object_id' may cause serious problems`
in the `TransactionCallbacksTest` that have been added via rails#38990 .

I prefer not to allow `warning: redefining 'object_id' may cause serious problems` warning everywhere
because generally overriding object_id should not be done.

Refer to
ruby/ruby#11834

Fix rails#53266
