Add way to call hooks for tests running in coroutines

[marcoskubis]

I know that is not the best way to to this, but this is just a suggestion.

While trying to run tests inside database transactions the setUp and tearDown hook does not work becouse the test is runing in a coroutine implemented by the RunTestsInCoroutine trait.

Adding these hooks we can do this:

use Hyperf\DbConnection\Db;

trait DatabaseTransactions
{

    public function beforeTestInCoroutine(): void
    {
        Db::beginTransaction();
    }

    public function afterTestInCoroutine(): void
    {
        Db::rollBack();
    }
}

And add the trait for each file test:

class ExampleTest extends TestCase
{
    use DatabaseTransactions;

    public function test_example(): void
    {
        // perform some insert operation
    }
}

How about that? What do you all think?
