EA-1071353 Filter out null elements in ProjectViewImpl.SelectionInfo.create

Browse Source 
Likely the exception happens because something is invalidated or disposed.
We can safely ignore nulls here, the worst that can happen is that some
element won't be re-selected properly, which is still much better than
an exception being thrown, and at least other, still valid, elements
will be re-selected.
