\complexnum and complex-root-position

[jmollera]

In version 3 the option complex-root-position = before-number does not work when the number has only imaginary part.

\sisetup{
    output-decimal-marker = {,},
    output-complex-root = \ensuremath{\mathrm{j}},
    complex-root-position = before-number
}

\complexnumber{0,4 + j 0,3} --> 0,4 + j0,3 (CORRECT)

\complexnumber{j 0,1} --> 0,1j (INCORRECT)
