Previously it matched the behavior of standard ActiveRecord after_commit callbacks. They do not work well within `joinable: false` nested transactions. Now `DB.after_commit` callbacks will only be run when the outermost transaction has been committed. Tests always run inside transactions, so this also introduces some logic to run callbacks once the test-wrapping transaction is reached.
