couchDB database creation part.
First, we check if a database with the name specified already exists. If yes,
this database will be destroy before creating the new one (with the same name).
function dropDB() {
    nano.db.destroy(nameDB, function (err) {
        if (err && err.statusCode != 404) {
            logger_1.logger.log('error', `When destroying ${nameDB} database : \n`);

        }
        nano.db.create(nameDB, function (err) {
            if (err) {
                logger_1.logger.log('error', `During creation of the database '${nameDB}' : \n`);
                throw err;
            }
            logger_1.logger.log('success', `Database ${nameDB} created \n`);
