Node.scaleNode fails to work on freshly created nodes not yet added to the document node tree. It doesn't work if I scale the node then add it to the tree. It works as expected if I add the node to the tree then scale it.

```python
from krita import *

def loadImageToNode(image: QImage, node: Node) -> None:
    # The format is hardcoded. Maybe condition on it later.
    image.convertToFormat(QImage.Format_ARGB32)
    w = image.width()
    h = image.height()
    size = 4*w*h
    imageData = image.constBits().asstring(size)
    node.setPixelData(imageData, 0, 0, w, h)

doc = Krita.instance().activeDocument()

image = QImage('<path to image>')
node = doc.createNode('asdf', 'paintlayer')
loadImageToNode(image, node)

activeNode = doc.activeNode()
parentNode = activeNode.parentNode()
parentNode.addChildNode(node, activeNode)

r = node.bounds()
node.scaleNode(QPointF(0,0), int(r.width()*0.48), int(r.height()*0.48), 'Bicubic')
print(int(r.width()*0.48), int(r.height()*0.48))

doc.refreshProjection()
```
