Summary: polarform of zero returns atan2

Initial Comment:

(%i1) polarform(cos(x)^2 + sin(x)^2-1);
(%o1) %e^(%i*atan2(0,sin(x)^2+cos(x)^2-1))*abs(sin(x)^2+cos(x)^2-1)

(%i2) trigsimp(%);
atan2: atan2(0,0) is undefined.

Message:
Are you expecting polarform to simplify its arg?  Otherwise, I kind of
think this is expected.
