None Selected

Hello,

Defining a selectbox like this :
select = st.selectbox("title", ("A", "B"), index=None)
... I get a KeyError exception at main.py:162
This is caused by the default "None" value. It is changed into an empty space by "replace_empty(...)", but
if selected != st.session_state.state_dict.get(label, None): goes into the "true" statement, and causes an exception.

The fix at main.py:161:
if selected != st.session_state.state_dict.get(label, " "):

I make a PR or let you fix ...

@hansipie is this still relevant?

Hello.
First of all sorry for the delay ...
Yes it does... this is a sample to reproduce:

import streamlit as st
import streamlit_analytics2 as streamlit_analytics

with streamlit_analytics.track():
    options = st.selectbox("options", ("option 1", "option 2"), index=None)
    st.info(options)

The fix I proposed was a first idea and needs to be explored further.

PS: Thx for this fork :)
