ExpireAfter Testing Rework

[JakenVeina]

Reworked testing for all versions of the ExpireAfter operator, to improve functional coverage and cover various existing defects.

This will support the effort to fix #716.

[JakenVeina]

This is the test that leverages the new TestScheduler class.

[RolandPheasant]

This is clearly very well considered testing. I do not understand every detail atm, but the tests pass and that's good enough for me.

In the near future I will step into the tests to familiarise myself with the fine grained details.
