GF-35208: fix dispatch system so delgated events are only dispatched to the immediate owners

* make meaning of "delegate" property on event the destination object, not the source
* Remove unused code from the old delegation system.
* Include test case from this bug report in ComponentDispatchTest.js

Restore previous interpretation of delegate property -- needed to have correct sender.

* Added test for redispatch to detect this error.
