0033648: Modeling Algorithms - Bad partition result

Browse Source 
Removed unnecessary tolerance increase for Line\Line intersection.
Tolerance increasing logic for some specific curve types
  was added with #26619.
Original fix had no test for Line/Line case and
  theoretically was added as a possible issue.
After research Line/Line case doesn't need a special tolerance case.
