related tdf#165521 oox: ShapeExport::GetNewShapeID of at least 2

This patch fixes an existing bug that was exposed in 7.6.5
by commit bff76421e234df7246a7f49c71a11432f86e09d1.

Microsoft Powerpoint was complaining that my unit test
tdf165521_fixedCellHeight.pptx
needed to be repaired after round-tripping it in LO.

While notesMaster1.xml didn't mind two shapes having the same id=2,
it complained if the first one was set to id=0 or id=1.

However, we can see the same situation in other files
(like slidesMaster1.xml) where there is no complaint,
like in tdf106867.pptx.

So I don't know what really is going on,
but it makes sense to not have overlapping unique IDs,
and thus this patch "just works",
which is enough to make me happy.
