When I updated, my build target for `FormatTests` stopped working.
```
ninja -C build clang-format FormatTests
ninja: Entering directory `build'
ninja: error: unknown target 'FormatTests'
```

I'm trying to figure out what changed or how to modify my workflow. I think I ran this PR with stale tests.
