Moved the Chat Completion buffer into the StreamingUnifiedChatCompletionResults so that all Chat Completion responses can benefit from it. Chat Completions is meant to adhere to OpenAI as much as possible, and OpenAI only sends one response chunk at a time. All implementations of Chat Completions will now buffer. This fixes a bug where more than two chunks in a single item would be dropped, instead they are all added to the buffer. This fixes a bug where onComplete would omit trailing items in the buffer.
