[bug] connection is still open after saving the models

[TBD]

problem:

• Dupa ce apelez "node index.js", nu stium cum sa ma exprim, dar "it still hangs", adica in terminal nu reapare prompt-ul, insa in baza de date se adauga corect si functioneaza.

hints:

• https://mongoosejs.com/docs/api/connection.html#connection_Connection-close
• https://mongoosejs.com/docs/api/model.html#model_Model-save
• add a console.log(...) after save methods

Fixed.

mongoose.connection.close() is a whimsy function. :)
