mp-serializer: fix scientific presentation of complex numbers
So that z = re(z) + im(z) will be displayed with the "+" in scientific notation.
In mp_serializer_to_string: DISPLAY_FORMAT_AUTOMATIC I removed the workaround for this issue, so
big (or small) imaginary numbers will be displayed in scientific notation again
(as against fixed notation before) automatically.
