Async Reactor/Projector issue

[dilab]

Currently for all Async Reactors/Projectors are processed by a single job HandleStoredEventJob.

That means one projector/reactor's failure will make the rest fail too. I am aware that we can catch all exceptions by the catch_exceptions key. However that will make the laravel queue retry mechanism useless.

I propose to use fire different job for each projector/reactor's, so they can handle their own fail/success.
