fix tracking center with newer proxmox-widget-toolkit

newer widget-toolkit versions did change the DateTimeField a bit, and
now breaks when there is no viewModel anywhere, so add one as a stopgap
fix for now in the tracking center.

the real fix would have to be in DateTimeField itself, probably checking
if there is a bind.
