Do not call recalculate_sizes while clearing a client session because it 

needs to loop over the clients, instead do it after all clients are
cleared. Fixes a crash reported by martijn@ when a session with multiple
clients attached is destroyed, but there are other sessions so tmux does
not entirely exit. ok deraadt
