workspace: Handle child not being present in the window slots array

Browse Source 
Adding children to the WorkspaceLayout without calling addPreview() is
not supported, so let's log an error in case that happened.

We also have to allocate that child an empty ClutterActorBox, otherwise
Clutter will complain loudly.
