Invalid warning about unclosed multipolygon

[delta_foxtrot2]

The validator plugin should check to see if all members are present in a multipolygon before warning about it being unclosed.

Fixed in the attached patch.

Sorry, submitted the patch to the wrong ticket. Nevertheless, the attached example contains unclosed ways, but doesn't reveal this bug. I think, this fixed in the meanwhile, isn't it?

The following snipped from MultipolygonTest should take care of not warning about unclosed+incomplete multipolygons.

for (RelationMember rm : r.getMembers()) {
    if (!rm.getMember().isUsable())
        return; // Rest of checks is only for complete multipolygons
}
