test: let the search-parity corpus past the anti-spam filter

The fixture re-recorded in #4299 holds the same long-form article posted
by two authors. LocalCache's anti-spam filter keeps the second copy out,
so anAddressableKindComesBackThroughTheAddressablePath could never find
it and main went red. The class tests the filter path, not spam policy:
switch the filter off while loading the corpus and restore it after,
since LocalCache is shared with the other test classes.
