fixes #293
@antifuchs @gustavosoares @aerickson @suhlig @danrue Can you verify?

Previously, without this fix, I tried printing versions using the following code piece:

def get_individual_versions(versions, folder_path, log_file, grafana_url, http_get_headers, verify_ssl, client_cert, debug, pretty_print):
    file_path = folder_path + '/' + log_file
    



    # I added this part
    #########################
    with open("versions.txt", "w") as f:


        f.write(f"{folder_path} -> {repr(versions)}\n")
    #############################
    
    if versions:
        with open(u"{0}".format(file_path), 'w') as f:
            for version in versions:
                print(f"{{  versions: {type(version)}: {version} }}")
                (status, content) = get_version(version['dashboardId'], version['version'], grafana_url, http_get_headers, verify_ssl, client_cert, debug)
                if status == 200:
                    save_version(str(version['version']), content, folder_path, pretty_print)
                    f.write('{0}\n'.format(version['version']))

and we needed access to versions['versions'].

@ysde Can you take a look at this?
