Disconnect users when session is reseted

Disconnecting users

We are trying to disconnect all users when the session must be reseted.
The chosen way to do it crashes the server, see commit : cf3e0dd

See bellow error :

E-Quizz\server.js:421
       socket.disconnect();
       ^

ReferenceError: socket is not defined

Node server crashes

Node server crashes when no student is connected and the teacher tries to start the session anyway.

To reproduce error :

Do not register any student
Create a session
Try to start a session (wont work since there is no student connected
refresh the page (teacher)

--> Teacher is asked to create a session (which should already be done), and nothing happens when clicking "Créer la session", bellow error appears :

See error below :

/server.js:130
                     client.to('boitier').emit('test', quizzQuestionsAndAnswers[1][questionNumber - 1][3]);
                                                                                                      ^
