twisted.test.test_internet.TimeTestCase.testCallLaterDelayAndReset shouldn't use reactor.iterate()

New submission from danderson <None>:

It uses reactor.iterate() through the Clock test helper, defined in `twisted.test.time_helpers`. Removing this use of reactor.iterate should take one of two roads:

1. Make Clock not use reactor.iterate, and rewrite tests using Clock to be more event-driven.
1. Make this one test not use reactor.iterate, and let tests outside of test_internet use reactor.iterate happily.

The road to take depends on what the desired end state is regarding use of reactor.iterate in tests: eliminate from test_internet, or purge completely?

Reassign the task to me with the decision, and I'll implement.
