This CL renamed browser/chromeos/settings/signed_settings_cache_unittest.cc to
browser/chromeos/settings/device_settings_cache_unittest.cc and removed the old
file from chrome_tests.gypi but didn't add the new name. The file has been
missing from build files ever since. Do you want to try to add it to
chrome/browser/chromeos/BUILD.gn and see what it takes to get it to compile and
paass?

Uh, good catch. I can take a quick look to see whether this situation can be
rescued. Fortunately the file is rather short! ;-)
