More robust Selection view title computation
Currently if the Selection view or more specifically class PropertyPage
view computes a new title and is given a resource that contains e.g. a large literal value, the title computation will produce an unsuitably long, potentially illegible String as the title.
The code should check whether the specified resource(s) to compute a title from have L0.HasName
and/or L0.HasLabel
before using NameUtils.getSafeName/Label
on them. Also, if no Name or Label exists, the view should just use the default "Selection"
title value.
