[1.x] Fixes server shutting down on concurrently when exceptions are reported at root level of the task

[nunomaduro]

This pull request fixes an issue introduced when migrating to https://github.com/laravel/serializable-closure, where errors reported from concurrently ( at the root level of the task ) were causing the server to shutdown.

Fixes #418

@nunomaduro did you tested it after the PR ? I still get exception and receive the report from Handler

[nunomaduro]

Can you share your "composer.lock" file? @foremtehan

[nunomaduro]

@foremtehan I mean only the contents of the "composer.lock" file please.

[nunomaduro]

Please share the full error you are getting now.
