tester package retrieves no objects for List when not providing namespace

[jacobdonenfeld]

func (c *Client) List(ctx context.Context, objList kclient.ObjectList, opts ...kclient.ListOption) error {

...

var ns string
	if listOpts.Namespace != "" {
		ns = listOpts.Namespace
	}

	// put objects into a map because c.objects() returns both created and updated objects, with updates coming after
	// created. this will ensure the last object in is what is returned
	resultObjs := make(map[string]runtime.Object)
	for _, testObj := range c.objects() {
		if testObj.GetNamespace() != ns {
			continue
		}

if a namespace is not provided in ListOptions, it is set to an empty string, which will not match testObj.GetNamespace(), resulting in no items fetched.
