#8498: bug in has_good_reduction for a point on an elliptic curve over a number
field

Comment(by cremona):
This is weird: I evaluate a polynomial f in K[X,Y,Z] at a triple [x,y,z],
but the value lands up not in K but in K[X,Y,Z] again (as a constant
polynomial, rather than an actual constant in K). This is not what the
{{{_call__}}} function for multivariable polynomials says. I can fix this
here, but it is symptomatic of a deeper problem.
