Bug: Calling /vars or /v adds new snippets to /list.

[andrei.eremeev]

Hi REPL team,

-> double a;
|  Added variable a of type double

-> a + 10
|  Expression value is: 10.0
|    assigned to temporary variable $1 of type double

-> /list

    9 : double a;
   10 : a + 10;


-> /vars
|    double a = 0.0
|    double $1 = 10.0

-> /list

    9 : double a;
   10 : a + 10;
   11 : a;
   12 : $1;
