QmlPuppet: Enable negative scaling in multiselection

Browse Source 
Scenerotation was queried from the node for each drag move, causing
drift in the calculations. Locking the rotation at drag start makes
negative scaling work nicely.

Also enabled negative values on all axis scaling, since it makes no
sense to block it there when single axis/planar scaling already allows
it.

Fixes: QDS-4493
