stl_stats are newly only accessed by TriangleMesh::stats(),
most of the direct access to TriangleMesh::stl is gone with the exception
of parsing input files (3MF, AMF, obj).
Steps to repro:
1. Create some object with several parts.
2. Increase instances count.
3. Select some volume in ObjectList => all related volumes for each instance are selected in 3DScene (CORRECT)
4. Select last instance in ObjectList => all volumes (except one) of selected instance are selected in 3DScene (UNCORRECT).
ALL volumes of selected instance have to be selected in 3DScene
Fix: To avoid lost of some volumes in selection
check non-selected volumes only if 3DScene-selection mode wasn't changed
or there is no single selection in ObjectList
reset timestamp to 1. This led to a bug where e.g. deleting painted facets
through the respective item in object list followed by possible other actions
and undo restored the painted facets from the time when the project was loaded.
I'm not sure if there was any other situation where this problem manifested.
