Fix showing small item previews

Browse Source 
Don't use a clone of an actor that's not part of the scene graph for the
item previews. This patch fixes previews in the details pane for documents
for which we don't have full previews and for applications.

Use create_icon_texture() from AppInfo instead of looking up the file
for gicon when creating an application icon for the details pane.
