Use undo notification when deleting a card or badge

[piitaya]

Proposed change

Use notification with undo button instead of confirm dialog when deleting a card or a badge.
This PR also fixes some issues with notifications manager :

• Adding a new notification did not clear well the previous one
• The deleted notification wasn't always shown because the element that fired the event was deleted. It's fixed by adding showToast method on the lovelace object.
