Fix aot-test-generators usage

[inkless]

The test generated are missing the ending bracket:

describe('TSLint - .', function() {
  it('errorFile1.ts should pass tslint', function() {
    // test failed
    var error = new chai.AssertionError('errorFile1.ts should pass tslint.\\nERROR: errorFile1.ts[1, 17]: trailing whitespace (no-trailing-whitespace)');
    error.stack = undefined;
    throw error;
  });

it should be:

describe('TSLint - .', function() {
  it('errorFile1.ts should pass tslint', function() {
    // test failed
    var error = new chai.AssertionError('errorFile1.ts should pass tslint.\\nERROR: errorFile1.ts[1, 17]: trailing whitespace (no-trailing-whitespace)');
    error.stack = undefined;
    throw error;
  });
});
