Don't refresh not yet realized widget in wxGTK wxDataViewCtrl.

Browse Source 
If the text of any of wxDataViewCtrl cells was set before the control was
realized (e.g. during its creation), the code tried to refresh the not yet
shown widget resulting in GTK+ errors.

Avoid this by only refreshing the tree if it's realized.
