transaction option in codeception doesn't roll back database changes made in tests.

[myleshyson]

Description

I'm noticing that even though I'm setting transaction: true in codeception.yml, database operations made within tests aren't rolled back after the test is done. Here's the test file i'm running. There's no modules or plugins enabled for this test instance.

<?php

namespace tests\integration;

use Codeception\Test\Unit;
use craft\elements\Entry;
use tests\fixtures\LocationFixture;
use tests\fixtures\ProviderFixture;

class GmbModuleTest extends Unit
{
    /**
     * @var \UnitTester
     */
    protected $tester;

    public function testCreatedLocationTriggersQueue()
    {
        $section = \Craft::$app->getSections()->getSectionByHandle('locations');
        $location = new Entry();
        $location->sectionId = $section->id;
        $location->title = 'Some New Location';
        $location->typeId = $section->getEntryTypes()[0]->id;
        $location->enabled = true;
        \Craft::$app->getElements()->saveElement($location);
    }
}

Steps to reproduce

1. Write a test in which it creates a new entry.
2. See that after the test is done running, the entry still exists within the database.
