Coordinates skewed after Move Component into separate file

Reproduce:

1. QtC: Create a Qt Quick Hello World, make it 800x800
2. Designer: Create a rectangle, say 200x200 at 100,100 coordinates
3. Code: RightClic the rectangle->Refactoring->Move to Separate File

The new file has 100,100 coordinates making it move 100,100 pixels on each instance. The main qml has not set x,y coordinates

Expected:
The new file to have x,y coordinates as (0,0), the parent to have (100,100) applied to the instance.

This might be applied to anchors too.
