Issue Type: Bug

When I launch VSCode on Mac from the Applications folder or via Spotlight Search the path is not correctly set. This means that when I try to run tasks from withing VSCode they fail to find the command. I've confirmed this by creating a test task which is this:

{
	"version": "2.0.0",
	"tasks": [
		{
			"command": "echo $PATH",
			"type": "shell",
			"label": "test task",
			"problemMatcher": []
		}
	]
}

The output of this is /usr/bin:/bin:/usr/sbin:/sbin.

If, however, I launch VSCode from the terminal via open /Applications/Visual\ Studio\ Code.app then the path is set correctly.
