Freezing 1or2 shapes with 1or2 paths fails

[humdinger]

This is hrev31444.

Here are two scenarios where freezing a shape fails.

First scenario: 2 Shapes sharing 1 path:

1. Create a shape with a path and a style.
2. Select the path and add a couple of points.
3. Create a second shape and use the same path.
4. Move/resize/rotate the 2nd shape a bit.
5. Select "Shape | Freeze Transformation".

Now, the path should snap to the selected shape's new position/size/orientation. It doesn't. Instead the shape snaps to the original path's position.
If there's an issue, because the path is shared with another shape, the command to "Freeze Transformation" should be disabled.

Second scenario: 1 Shape from 2 paths:

1. Create a shape with a path and a style.
2. Select the path and add a couple of points.
3. Create another path.
4. Select this second path and add a couple of points.
5. Move/resize/rotate the shape a bit.
6. Select "Shape | Freeze Transformation".

Now, the paths should snap to the shape's new position/size/orientation. Instead only the second path snaps to the new location, the shape snaps to the original first path's position.
So for example, if you created the second path inside the first path, creating a hole in the shape, the hole stays put, while the rest of the shape snaps back to the original first path's location.
