[dev-italia] Bad import in Emilia-Romagna

[Martin Raifer]

PS: I tried to contact the original importer in a changeset comment:
https://www.openstreetmap.org/changeset/20349894, but didn't yet get a
reply.

PSS: Hmm… Maybe all of the sport_centre areas from the respective
import changeset could simply be reverted/removed: at first glance,
none of them looks like a real sport centre:
http://nrenner.github.io/achavi/?changeset=20349894
That way, we'd just need to find all affected changesets (there's at
least one more changeset, where overlapping forests&farmland were
uploaded).
