The MissingVerticalHorizontal functions from the Sketcher WB do not behave as expected. See #21396.
A check for redundant contraints is required if `makeMissingVerticalHorizontal()` is used. The argument for the function should be `True`. For consistency the same was done for makeMissingPointOnPointCoincident().
