Interesting - which case does that cover which wasn't covered before?

Interesting - which case does that cover which wasn't covered before?

This one. I stumbled onto this while digging deeper into what were the elements of a JobDefinition uniqueness.

Definition of a job with a standard "configuration" (passed through the parameter).
Temporary overriding of that job "configuration" at runtime through the one-of execution of the job.

    [Fact]
    public async Task InstantJobCanOverrideInitiallyDefinedParameter()
    {
        ServiceCollection.AddNCronJob(
            n => n.AddJob<ParameterJob>(o => o.WithCronExpression("* * 31 2 *").WithParameter("Hello from AddNCronJob")));

        var provider = CreateServiceProvider();
        await provider.GetRequiredService<IHostedService>().StartAsync(CancellationToken);

        provider.GetRequiredService<IInstantJobRegistry>().RunInstantJob<ParameterJob>("Hello from InstantJob");

        var content = await CommunicationChannel.Reader.ReadAsync(CancellationToken);
        content.ShouldBe("Hello from InstantJob");
    }

The other tests were added/modified to have a more comprehensive suite in that context.
