fix dataset update

[abidlabs]

Allows the samples in a gr.Dataset to be updated. Here's a quick example:

import gradio as gr

def update(value):
    print(value)
    return value, gr.Dataset(samples=[["a"],["b"]])

with gr.Blocks() as demo:
    with gr.Row():
        textbox = gr.Textbox()
        dataset = gr.Dataset(components = ["text"], samples = [["This"]], label="Saved Prompts")
        dataset.click(update, inputs=[dataset], outputs=[textbox, dataset])

demo.launch()

Closes: #8312
Closes: #7282
Closes: #6415

Also fixes the issue where clearing an Interface that included a Dataset would cause the Interface to crash.

Closes: #6807
