Allow Better Testing of Properites

[JonPurvis]

At the moment, if you have a job and you specified the number of times it should be retried, you could test it like this:

test('job')
    ->expect('App\Jobs\TestJob')
    ->toBeTriedAgainOnFailure()

However, that merely checks that a $tries property exists on the class and that the value is above 1. I think it would be better if you could specify that number yourself:

test('job')
    ->expect('App\Jobs\TestJob')
    ->toBeTriedAgainOnFailure(maxTries: 5)

If you have a set number that each job should be retried across the application, then this test will help catch where someone has tried to increase it.

There's definitely some other expectations that this can be applied to and I think it will greatly enhance Lawman
