benchmark-data-repository exists and isn't empty

[jellespijker]

We have two separate workflows, whom both use this action and I think they're interfering with each other when they both want to post their results as comment.

See error message:

/usr/bin/git -c user.name=github-action-benchmark -c user.email=github@users.noreply.github.com -c http.https://github.com/.extraheader= clone ***github.com/Ultimaker/CuraEngineBenchmarks.git ./benchmark-data-repository
fatal: destination path './benchmark-data-repository' already exists and is not an empty directory.

I think this should be fixed by #216 which got released today in v1.19.1
Could you please verify?
