Really fixed the atan2(-Pi, 0) bug.

The problem was that atan2_eval assumed that if y is real and not
positive, it must be negative. But this neglects the fact that in
symbolic compution it may just not be possible to determine the
sign. Now, the expression is returned as it is. Ugly, but correct.
