=head2 _fixReplyCount ( asset )

Fixes the mismatch in number of replies and lastPost in a thread and/or a CS that occurs after a cut or paste
action.

Note: if invoked on a thread the CS containing it will very likely be changed as well, but likely in an incorrect
manner. Therfore, after running this method on a Thread you probably also want to run it on the container CS.

WebGUI::Asset::Wobject::Collaboration.
