reveal = Never not respected when running task programmatically

[sergei-dyshel]

• VSCode Version: 1.30.2
• OS Version: Linux

Run the following code as part of extension:

      const task = new vscode.Task(
          {type: 'myExt'}, vscode.workspace.workspaceFolders[0], 'myTask',
          'myExt', new vscode.ShellExecution('ls'));
      task.presentationOptions.reveal = vscode.TaskRevealKind.Never;
      vscode.tasks.executeTask(task);

Despite reveal = Never the terminal is still shown when executing task.

P.S. This is not a dup of similar recent issue because this happens also with Python extension disabled.
P.S.S. Looks similiar to old issue #19810;

@sergei-dyshel, thank you for the example code. This only reproduces in stable. In insiders the issue is fixed already. Thank you for filing!
