get item from localStorage only when the cache is enabled

[LouaiTrabulsi]

I need to use the chatbot in an environment that doesn't support localStorage.
I saw you are using localStorage for caching purpose, for my case I don't need cache so I leave it as default (disabled), but I realized that in file 'storage.js' you are accessing the localStorage before checking if the cache is enabled:
const unParsedCache = localStorage.getItem(cacheName);
so I just moved this line to be after checking if cache is enbled:

if (cache) {
    const unParsedCache = localStorage.getItem(cacheName);
    if (unParsedCache) {

this way I will not get an error related to localStorage in my environment.
Thanks in advance
