[Tile-serving] [osm2pgsql] missing outer polygon(s) when diff update deletes a multipolygon relation (#67)

[apmon]

Yes, this is a long standing bug in the diff import code. It has been reported as https://trac.openstreetmap.org/ticket/4525
There also exists a patch to fix it, but so far it has never been committed, as the impact of it wasn't clear or if there is a better way.

However, as no one has done such an assessment or come up with a better way in the last 10 month, I will likely just go ahead and commit it soon and we will just have to live with the consequences to performance it entails.
