Task_Handler unit test, after completion time only

Browse source 
Unit test for task handler tasks that complete after delay time.
Required creating local reference for a clock.
All evennia unit tests pass with `evennia test evennia`.
All of my projects unit tests passed. They have a very heavy usage of reactor.
Verified delays working with project manually

Moving forward with creating method to call callbacks early.

deferLater creates an instance of IDelayedCall using reactor.callLater.
deferLater uses the cancel method on the IDelayedCall instance to create
the defer instance it returns.
