Fix EmptySourceFromEventIDs test configuration

[fwyzard]

PR description:

Fix the EmptySourceFromEventIDs test configuration.

The EventIDChecker module requires that events be created and analysed in a specific order, which cannot be guaranteed in a multi-stream, multi-threaded configuration.

PR validation:

The TestFWCoreModulesEmptySourceFromEventIDs unit test should now pass.

This PR only touches unit test TestFWCoreModulesEmptySourceFromEventIDs which should now work fine as events are processed in serial mode and should match the order defined in https://github.com/cms-sw/cmssw/blob/master/FWCore/Modules/test/testEmptySourceFromEventIDs_cfg.py#L5-L30
