[ic] tmpscratch vars not destroyed after page is processed

[Brian Kosick]

Hi All,
    I don't know if anyone else has expierienced this.....

On the saved carts page, it never seemed top work right, you could 
delete the cart, it would still show up in the browser, but it would be 
removed (correctly) from the DB.  leading to some very strange behavior, 
and lots of confusion with clients.  After some head banging, I finally 
figured ou that my TmpScratch vars did not seem to be destroying 
themselves after the page was proccessed.  As a quick fix, I added

[calc]
  $Scratch->{saved_carts_carts} = '';
  $Scratch->{saved_carts_recurring} = '';
[/calc]

to the bottom of the saved_carts page, and everything works correctly 
now, so no more instances of the browser thinks it's (the 
savedcart/recurring order) there when it's not.  It is an issue with all 
of my IC sites, which are (mostly) based off the Foundation demo.  I 
haven't modded saved_carts.html up until this point.  Could this be a 
bug in the demo?

I'm using
IC 4.8.7
RaQXTR
perl 5.6.1
