Merge "Android: SELECT popups should not send notifications if a renderer asked to close it." to M51 branch.

A renderer clears references to ExternalPopupMenu when it asks to close
(FrameHostMsg_HidePopup). So, another ExternalPopupMenu could receive the
notifications.

OSX, which is another platform using ExternalPopupMenu, doesn't send
notifications on close by FrameHostMsg_HidePopup.
