Fix infinite requests when doing tab item select

[freddyaboulton]

Description

Fixes #2069

To test, run the reproducer and switch tabs successfuly. blocks_plug also works as expected.

import gradio as gr
    
tab_names = ["one", "two"]

with gr.Blocks() as demo:

    with gr.Tabs():
        for name in tab_names:
            with gr.TabItem(name) as rl_tab:
                num = gr.Number()
                rl_tab.select(lambda: 3, inputs=[], outputs=[num])

demo.launch()

Don't think this breaks anything but would be good to get the opinion of a front-end expert.

TBH not sure how the old code was causing the original problem but it seems to be fixed now 😬

Can confirm that the demos work, but it would be good to get some confirmation from the front end team: @aliabid94 @dawoodkhan82 @pngwn?
