Hey there, extracting a custom track from an existing cluster I faced a strange behaviour. Rally extracts 1001 docs while it should extract exactly 1000 docs. When I try to import it with the flag --test-mode I get this error: > [ERROR] Cannot race. Error in track preparator > Data in [/rally/tracks/index-documents-1k.json] for track [tracks] are invalid. Expected [1000] lines but got [1001]. I have to open manually the json file and remove the latest document. After that it works. Is it a bug or anything else? ---

I confirmed this is a bug. Raised [Wrong amount of docs for test corpora when creating a track with create-track 路 Issue #1317 路 elastic/rally 路 GitHub](https://github.com/elastic/rally/issues/1317) and will raise a fix PR soon. ---
