Turn tasks scheduled on the `v8::Isolate` or on the given platform into no-ops if the underlying `MainThreadInterface` has gone away before the task could be run (which would happen when the `Environment` instance and with it the `inspector::Agent` instance are destroyed). This addresses an issue that Electron has been having with inspector support, and generally just seems like the right thing to do, as we may not fully be in control of the relative timing of Environment teardown, platform tasksexecution, and the execution of `RequestInterrupt()` callbacks (although the former two always happen in the same order in our own code).

I’m reviewing from the phone so I am not sure if I captured the details of the change. It looks like this is the scenario where MainThreadHeandle is supposed to be used... I will try to do a better review this weekend. |

@eugeneo Take your time :) I’m not sure how |
