Error using vscode Tasks presentationOptions reveal

[brianignacio5]

Bug Description:

Trying to test a vscode extension in Theia but get some errors with vscode.Task.PresentationsOptions.reveal. As I understand, this is already covered by Theia in VSCode API coverage.

Steps to Reproduce:

1. In visual studio code extension, use the vscode.task API to create a task.
2. Try to update myTask.presentationOptions.reveal = vscode.TaskRevealKind.Always;
3. Get an error that can't update reveal of undefined

vscode extension code

public static addTask(
    taskDefinition: vscode.TaskDefinition,
    scope: vscode.TaskScope,
    name: string,
    execution:
      | vscode.ShellExecution
      | vscode.ProcessExecution
      | vscode.CustomExecution,
    problemMatchers: string | string[],
    revealTask: vscode.TaskRevealKind
  ) {
    const newTask: vscode.Task = new vscode.Task(
      taskDefinition,
      scope,
      name,
      ESP.extensionID,
      execution,
      problemMatchers
    );
    newTask.presentationOptions.reveal = revealTask; // Error here
 }

I believe its an issue with the new vscode.Task() constructor not initializing it.
