$wgAllDBsAreLocalhost was removed 3 years ago, in I54b23654. This maintenance script kept working because it just saw null for the variable. But then Id67d0759 changed the code to access it via Config, which does checking for accessing of nonexistent config vars and so broke things. Bug: T232268 Change-Id: I4fc39cccfd9041c76f734a1a85c2b34fc84218f0
