Subject: [PATCH] Sketcher: Auto Update Mode bug fix

==================================

Bug:
http://forum.freecadweb.org/viewtopic.php?f=10&t=11341&start=60#p92422

Why?
- When coding Auto Update Mode I forgot to solve the sketch when the constraint is cancelled to restore the solver level constraints.
