Delete collection and delete item from collection does not seem to work.

[Rickrat]

Describe the bug Deleting collections does not work for me.

To Reproduce

1. Get a list of collections
2. foreach one, loop through the items and remove them from the collection
3. finally delete the collection

Expected behavior I expected the collections to be deleted. However, after it runs without exceptions, the collections are there, still intact.

Side Note: There is a TODO throw in ApiService line 145 which I had to comment out to get this to function at all.

Here's my code:

var server = factory.CreateServer();
string url = server.Uri.ToString();

try
{
    var libs = await server.Libraries();
    var movies = libs.Single(c => c.Title == "Movies");

    var collections = await factory.PlexLibraryClient.GetCollectionsAsync(server.AccessToken, url, movies.Key, string.Empty);
    foreach (var col in collections.Collections)
    {
        var items = await factory.PlexLibraryClient.GetCollectionItemsAsync(server.AccessToken, url, col.RatingKey);
        foreach (var item in items.Media)
        {
            await factory.PlexLibraryClient.DeleteCollectionFromLibraryItemAsync(server.AccessToken, url, movies.Key, item.RatingKey, col.Title);
        }

        await factory.PlexLibraryClient.DeleteCollectionFromLibraryItemAsync(server.AccessToken, url, movies.Key, col.RatingKey, col.Title);
    }

}
catch (Exception ex)
{
    string msg = ex.Message;
}

I'll take a look. I'll also add a better unit test around Collections
