[hooks] fix extra_props handling on python3
The json module expects str, not bytes, so we need to do the decoding.
$(document).ready(function() {
QUnit.module("air");
QUnit.test("test 1", function (assert) {
assert.equal(2, 2);
});
QUnit.test("test 2", function (assert) {
assert.equal('45', '45');
});
QUnit.module("able");
QUnit.test("test 3", function (assert) {
assert.deepEqual(1, 1);
});
});
