Installation is incomplete when the folder contains a README

[SimonPlaye]

How to reproduce

1. Create a folder with a README
2. Start the Sicarator with yo sicarator within that folder
3. Enter the parameters
4. When asking whether the README should be overwritten, enter yes

What happens

The Sicarator abruptely stops after allowing to overwritte the README (no files and folder are created and generated and no package is installed). Some files are still created (with the pre-commit config for instance).
