test(er): fix broken exception ID asserts

The changes in #11772 broke ER tests that were relying on the old
exception ID tag. The rerun mechanism made the test pass on re-run so
the failure was not caught and the change was merged. Only the tests
were impacted, there was no impact on user-facing functionalities.
