[5.6] Add dispatchNow to Dispatchable Trait.

[jrseliga]

@taylorotwell I wasn't sure if tests were necessary, as BusDispatcherTest@testDispatchNowShouldNeverQueue seems to cover this.

[devcircus]

the dispatch method, in Dispatchable, defers to dispatchNow if the job isn't queued.

[jrseliga]

@devcircus I was under the same impression based on information I found on stackoverflow and Laracasts forum.

I see the dispatchNow fallback behavior on Dispatcher@dispatch, however, executing a Job from within a Controller for example, that is meant to perform an action and return data back synchronously is actually returned with an instance of PendingDispatch

Perhaps I've just missed something obvious?

[devcircus]

Ahh yes for Dispatchable, that is true. The DispatchesJobs trait is included by default in the base controller and has both "dispatch" and "dispatchNow".
Also, I tested on a project I'm working on and had forgotten I had made a custom dispatch method that handled async and sync jobs.
