Patch Rake::Task#execute instead of Rake::Application#display_error_message

[TylerRick]

This is based on how https://github.com/airbrake/airbrake/blob/master/lib/airbrake/rake.rb does it.

Fixes #26

[TylerRick]

Someone should just fork Airbrake and replace Airbrake-specific things with ExceptionNotifier. That way we benefit from all the work they do upstream (Airbrake) — including all their test coverage!

[TylerRick]

Manually tested using https://github.com/TylerRick/exception_notification-rake_example_with_spring/tree/workaround_using_execute_patch

Would be nice to have integration tests like Airbrake has. I really wonder if forking Airbrake would be the most efficient route.

Another unexpected benefit of this PR is that it appears to use my local time zone now. (I'm not sure why this changed ... maybe ExceptionNotifier uses the timestamp key if it is passed in the data hash?)

Before:
A RuntimeError occurred in background at 2019-05-21 01:16:26 UTC :
Now:
A RuntimeError occurred in background at 2019-05-20 18:16:44 -0700 :

Thanks @TylerRick - this is quite a fundamental change. Agreed that having integration tests would be really useful for this kind of thing. Do you have any ideas how to achieve that?

Can you also rebase this on top of master so we get a clearer diff (your other PRs are merged)?

[TylerRick]

All right, it's rebased :)

It's basically just copying how they do it in https://github.com/airbrake/airbrake/blob/master/lib/airbrake/rake.rb, since they no longer do it the way they used to (the way that originally inspired this gem, I believe)...

[TylerRick]

All right, it's rebased again!

FYI: This PR (and this gem in general) may be redundant now that smartinez87/exception_notification#536 has been merged
