[BUG] Can't Plot Multiple Complex Series

[bgreber]

Details

Plots has always allowed plotting multiple series in a single call to plot such as:

x = [1;2];
x2 = [3;4];
plot([x x2]);

I have just updated my julia packages for the first time in about a year and found that this no longer works with complex series.
The following code

using Plots;
plotly();

x = [1+0.5im; 0.5+1im];
x2 = [2+2im; 3+3im];
plot([x x2]);

produces

Stacktrace is similar on every backend tested.

Technically you can still do multiple complex series by manually calling plot! for each one, but this is rather cumbersome.
