Fix the last test

Test was looking for `lineTo` as a substring of the input KCL program.
But there's no more lineTo function, so I changed it to look for
line() with an endAbsolute arg, which is the new equivalent.

Also changed the getConstraintInfo code to look up the lineTo if using
line with endAbsolute.
