Outline for leisure=sports_centre and stadiums missing

[HolgerJeromin]

Sports_centre has no fill/stroke color, so the outline is not visible. I think this is a regression.

The definition and the code says this should have a fill color.

Edit:
Same for leisure=stadiums

It has a fill but should probably also get an outline at the higher zooms (though not from z13 as it is currently rendered for other areas with the same color).

What if the outline would be green instead of brown (as in schools or hospitals)?

Fixed with #2574 (I don't know why this issue was not closed automatically).

This issue was mentioned in a comma separated list. That's why it was not closed by github itself.
