What are you seeing?

When running multiple targets via the RunTargets method in dotnet cake v3.0.0, the SetupContext.TasksToExecute property passed to the script's Setup delegate only lists the tasks that will be run for the first target specified, rather than the tasks to run for all specified targets.

What is expected?

I would expect the SetupContext.TasksToExecute property to contain all tasks that will be run across all specified targets rather than just the first target.

Steps to Reproduce

Setup(context => {
    Console.WriteLine($"Tasks to run: {string.Join(", ", context.TasksToExecute.Select(x => x.Name))}");
});

Task("A").Does(() => {
    Console.WriteLine("Running A");
});

Task("B").Does(() => {
    Console.WriteLine("Running B");
});

RunTargets(new [] { "A", "B" });

Resulting output when running dotnet cake is:

----------------------------------------
Setup
----------------------------------------
Tasks to run: A

========================================
A
========================================
Running A

========================================
B
========================================
Running B
