Only animate the message tray items on a hover of a new item or when the tray is left

This makes the animation feel more stable and keeps the left-most item expanded
when you move the mouse to the left in the tray.

The following behavior details are implemented by this patch:
  - we wait to collapse an expanded item till after the tray is hidden if
    we are hiding the tray
  - we don't collapse an expanded item if the summary notification associated
    with it is being shown, unless a different summary item is hovered over
  - we don't consider the mouse hovering over a summary notification as
    hovering over the tray, which allows us to collapse an expanded summary
    item if it is not associated with the summary notification being shown
