So, I just learnt from #5518 that pre-expansion lints are going to be deprecated in rustc, so maybe merging this is not the best idea 😢 I'm not sure if there is a way to catch active attributes after they are removed during expansion, so this lint may not be possible anymore. |

cargo-ui tests: check that <dir>/src exists before processing test I forgot that I had fixed this in a PR I closed some days ago (#5643). Before this change, cargo UI tests could fail when switching between branches if the previous branch had a test that the current branch does not have. The directory is not removed when switching because an ignored `Cargo.lock` file exists, and the code was trying to reach `$DIR/src` unconditionally. This change will just skip a directory that has no `src` subdirectory. changelog: none
