Conversion of existing git repo to renku overwrites readme

@Kriegelw just told me that when he ran renku init to convert an existing git repo to renku, the readme.md was replaced by the generic renku one. This is a bit annoying. Would it be possible to return a warning if there is a readme.md present already and enable skipping creation of the generic readme.md?

@schymans I just tried to replicate this in a local repository on my computer and could not.

I did the following:

~ mkdir test-repo
~ cd test-repo
~ git init
~ echo "# Test Repo" > README.md
~ git add README.md
~ git commit -m "Add readme"
~ renku init

Renku did not overwrite the contests of my README.md file.

Perhaps you have an older version of the renku CLI where this was indeed an issue.

I did the above with 0.16.0. Which version do you have? You check which version you have by running renku --version.
