tormes_setup should ignore/remove pre-existing tormes-setup-warnings.log

[mglubber]

For tormes v1.3.0, tormes_setup should remove or overwrite existing tormes-setup-warnings.log in the same directory. As the setup currently runs, if there is a pre-existing tormes-setup-warnings.log with errors in it, it will say that the setup failed, even if everything completed successfully.

Hi @mglubber You are definitely right. We will correct this behaviour in the next release. Really thanks for notifying this! All the best, Narciso
