New description:
Don't fail in `sage.sat.boolean_polynomials.learn_sat` when nothing was
learnt.
For example, this code should not fail:
{{{
sage: P.<a,b,c> = BooleanPolynomialRing()
sage: F = [a*c + a + b*c + c + 1, a*b + a*c + a + c + 1, a*b + a*c + a +
b*c + 1]
sage: from sage.sat.boolean_polynomials import learn as learn_sat
sage: learn_sat(F, s_maxrestarts=0, interreduction=True)
}}}
