The breakage was because: - aosp/1818236 removed the "rm -fr" invocation from the Ninja file that removed the old queryview tree - queryview files were created with permissions 440 to discourage manual editing These two together made incremental queryview invocations not be able to overwrite its output files. (Of course, it also made them incorrect since old files were lft in place) Test: Presubmits. Change-Id: Idaa3e1db82c9eb8325c48e37aca5146e69af7333
