EVar with wrong type get parsed

```haxe
trace(printer.printExpr((new haxeparser.HaxeParser(ByteData.ofString('var x:String-;'), '').expr())));
trace(printer.printExpr((new haxeparser.HaxeParser(ByteData.ofString('var x:String->;'), '').expr())));
```

prints:

```
var x:String
var x
```

but I expect them to throw...
