The "highlight border" is the anti-aliasing pixels, that have an 
intermediate color between the subject and the background. To obtain a 
proper cut:
- select the background with the magic wand
- "Select/Grow" the selection by two pixels
- Use "Colors/Color to alpha" and the the background color as the color 
to remove

This will remove the background, and make the antilaliasing pixels 
partially transparent.

To put another color in the background:

- add a new layer
- move it under your subject
- bucket-fill with the required color

The partially transparent border pixels obtained above will create the 
proper color blend for a smooth border.
