[turtle] Fixed remanent images bug

Browse Source 
We now erase the turtle before writing text. This way we can redraw it
on top of it, preventing overlapping and remanent images.

Those scripts are causing issues :
goto(-30,50)
write('coucou')
left(270)
goto(30,50)
write('oui')
-----------
up()
goto(-30,50)
write('coucou')
goto(30,50)
write('oui')
