I applied your patch, but I don't think it does the right thing.
Isn't it trying to create the (already existing) group from where the
function is being called rather than the target given by
nnmail-expiry-target?

I took a stab at modifying the patch but ran into some difficulties.
I'm not sure if one should check for the existence of the target group
in the function nnimap-expiry-target when it is possible that
nnmail-expiry-target returns a non-nnimap group.

Is it better to move the check inside nnimap-request-accept-article?
