[MapCSS] buildings not rendering in mapnik style

[wiktorn]

Since @8339 buildings in mapnik style (​https://github.com/bastik/mapcss-tools/tree/osm/mapnik2mapcss/osm-results) are not rendered correctly.

As far as I've checked the style hasn't changed for half a year. It looks like it is related to:
#11382 / [8297]

I've checked ​http://josm.openstreetmap.de/download/Archiv/josm-snapshot-8294.jar - and buildings are rendered properly.

With ​http://josm.openstreetmap.de/download/Archiv/josm-snapshot-8297.jar they are not.

This style should work, but does not in r8425:

way[building][railway!=station] {
    fill-color: #bca9a9;
}

I'll have a look at it tomorrow. My first idea would be that railway is considered to be a required key here (which it should not):

if (!Op.NEGATED_OPS.contains(keyValueCondition)) {

should be

if (!Op.NEGATED_OPS.contains(keyValueCondition.op)) {

I just tested it, the patch should fix the issue.

This should fix it.
