ter-newline-after-var does not work for nested vars

Used versions

TSC: 3.0.3
tslint: 5.11.0
tslint-reslint-rules: 5.4.0

Used tslint.json

{
  "extends": [
    "tslint-eslint-rules"
  ],
  "rules": {
    "ter-newline-after-var": [true, "always"]
  }
}

Linted code

const myFunc = () => {
  const x = 2;
  const y = 3;
  return x + y;
};

Actual behavior

No linter error

Note: Same behavior when I change the arrow function to just function: const myFunc = function() {...}

Expected behavior

The linter error "Expected blank line after variable declarations."

Analysis

If I change the const myFunc to a real function, the linter sees the problem:

function myFunc() {
  const x = 2;
  const y = 3; // ERROR
  return x + y;
};

I'm not experienced with tslinter implementations so I don't know if this information helps:
I found out that the function onNode (file: dist/rules/terNewlineAfterVarRule.js) is called only once with node.kind === ts.SyntaxKind.VariableStatement => true for the outer const.

Thanks for the help!

@webschik I checked the changes at your repository. It works, thx.
But it breaks the possibility to add additional blank lines:

const foo = 1;  // ERROR: Unexpected blank line after variable declarations.

const bar = 2;

Thanks, @Xenya0815 !
I specifically made this case to trigger the error, but Eslint allows it. I will fix that.
