Repositories with less than 4000 entries are always handled using a single thread, causing test-lazy-init-name-hash --multi to error out. Don't abort the whole test script in that case, but simply skip the multi-threaded performance check. We can still use it to compare the single-threaded speed of different versions in that case.
