dependsOn executes wrong tasks in multi-root workspaces

[dedChar]

Issue Type: Bug

Running tasks with dependencies in a multi-root workspace executes the wrong dependency tasks, if there are multiple tasks defined under the same label but in different root folders. VSCode will just pick the first occurance in the order of the root folders defined in the workspace settings.

To reproduce the issue:

1. Setup a simple multi-root workspace, e.g.

{
	"folders": [
		{
			"path": "root1"
		},
		{
			"path": "root2"
		},
		{
			"path": "root3"
		}
	],
	"settings": {}
}

2. In each root folder, add a tasks.json with two tasks. One task depends on the other. Example tasks of root1:

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "dependency",
            "type": "shell",
            "command": "echo 'This is the dependency task of root1'"
        },
        {
            "label": "main",
            "type": "shell",
            "dependsOn": ["dependency"],
            "command": "echo 'And this is the main task of root1'"
        }
    ]
}

root2 and root3 have the same tasks configured except that they echo their respective folder name instead.

3. Run task main of either root2 or root3.

Expected output for main of root2

> Executing task in folder root2: echo 'This is the dependency task of root2' <

This is the dependency task of root2

Terminal will be reused by tasks, press any key to close it.

> Executing task in folder root2: echo 'And this is the main task of root2' <

And this is the main task of root2

Terminal will be reused by tasks, press any key to close it.

Actual output on 1.65.1

> Executing task in folder root1: echo 'This is the dependency task of root1' <

This is the dependency task of root1

Terminal will be reused by tasks, press any key to close it.

> Executing task in folder root2: echo 'And this is the main task of root2' <

And this is the main task of root2

Terminal will be reused by tasks, press any key to close it.
