How to find the name of the recent card?

[David Bovill]

It is inconsistent.

If the recent card is updated after preOpenCard - then the current card
should behave the same. At the moment the recent cad and the current card
return the same result in a preOpenCard handler.

My use case is to create a quick handler which takes action depending on
where you have come from - so I need access to either the recent card, or
the current card in a perOpenCard handler. If I use and open card and let
there will be a small glitch / delay between displaying the card and
rendering the information the information.

Sure I can write ways around it that are complex - but I just want access
to the recent card or the current card :)
