bug 1066988 - [clock] unittest picker_test.js using assert.include for testing object, not Array or string

incorrect using assert.include!

test('shape:prototype ', function() {
    assert.ok(Picker);
    assert.include(Picker.prototype, 'reset');
    assert.include(Picker.prototype, 'value');

Picker.prototype - object not Array and not string.
chai used in test-agent simple do nothing in this case.

Write any value and test !!OK!!
assert.include(Picker.prototype, 'reset_reset');
