Describe the bug

I noticed in Rymdport (see corresponding issue at Jacalz/rymdport#142) that it wasn't possible to unfocus an Entry. I thought that it related to my extended entry (with accepts tabs instead of moving focus along) breaking something but I narrowed it down to widget.List not unfocusing other widgets in the case of it receiving a click that doesn't select any items.

How to reproduce

1. Start the example code below.
2. Focus the entry.
3. Try to click in between the list item and notice that the entry stays focused.
4. Now click the text at the bottom of the window and notice that it does unfocus correctly.

func main() {
	a := app.New()
	w := a.NewWindow("Hello")

	unfocus := widget.NewLabel("Try to click in an empty part of the list or on this text to unfocus!")
	focus := &widget.Entry{PlaceHolder: "Focus me first!"}
	list := widget.NewList(func() int { return 1 }, func() fyne.CanvasObject { return widget.NewLabel("Item") }, func(lii widget.ListItemID, co fyne.CanvasObject) {})
	w.SetContent(container.NewBorder(focus, unfocus, nil, nil, list))
	w.Resize(w.Canvas().Size().AddWidthHeight(0, 100))

	w.ShowAndRun()
}
