Description
Due to a recent change in the representation of the zero polynomial, I think the evaluate function is broken for the zero polynomial.
Currently if the evaluate method is called on a zero polynomial, it returns:
/usr/include/boost/math/tools/rational.hpp:191: U boost::math::tools::evaluate_polynomial(const T*, const U&, std::size_t) [with T = double; U = double; std::size_t = long unsigned int]: Assertion `count > 0' failed.

Also added a pull request on the github repo (https://github.com/boostorg/math/pull/50) since I was not sure which is the preferred method.
