Fix of https://github.com/prusa3d/Slic3r/issues/1631

Browse source 
This is a fix of a long standing bug, where an extrusion is incorrectly
drawn from the end of the last wipe move. Interestingly enough,
this bug is in Slic3r at least since 1.2.9, but lucky enough
it only occured for single perimeter, no infill prints with wipe after
retract enabled, and only if the two successive slices were discretized
exactly the same, which is quite unlikely.
