LineSeries do not show color of line stroke in legend markers

Steps to reproduce:
1. create a Plot or line chart without itemRenderers (null - no cross or points, dimonds, ...)
2. set the lineStroke style to a SolidColorStroke instead of a deprecated Stroke
3. add the legend and some data and run

</s:Application>

Actual Results:
The legend markers are always black

Expected Results:
They should be of the color defined for the lineSeries

Workaround (if any):
Override the private LineSeriesLegendMarker in LineSeries or set your own legend marker class

Solution:
add a test case in the LineSeriesLegendMarker for SolidColorStroke
if (fillStroke is SolidColorStroke)

{ color = SolidColorStroke(fillStroke).color }

else if (fillStroke is Stroke)

{ color = Stroke(fillStroke).color; }

else if (fillStroke is LinearGradientStroke)

{ var gb:LinearGradientStroke = LinearGradientStroke(fillStroke); if (gb.entries.length > 0) color = gb.entries[0].color; }
