Issue #3590487 by enomo103: Remove unused variable assignment in NodeJsonOutputTest.

Takuya Enomotorequested to merge
issue/metatag-3590487:3590487-unused-variable-in into 2.2.x

Closes #3590487

Removes the unused $response variable assignment on line 90 of NodeJsonOutputTest::testNode().

The value was immediately overwritten on the next usage by $this->getSession()->getPage()->getContent(), so only the $this->drupalGet($url) call (needed for the status code assertion and to populate the session) is kept.
