18969	Improve performance of validator checks	GerdP	team	"Some tests are executed for each element of the data set although they are only interested in tagged objects. Mosts tests which extend Test.TagTest should override method `isPrimitiveUsable()` like this to check `isTagged()` first:
{{{
#!java
    @Override
    public boolean isPrimitiveUsable(OsmPrimitive p) {
        return p.isTagged() && super.isPrimitiveUsable(p);
    }
}}}
to improve performance.
