API caching not checking for refreshed tokens

[EricNetsch]

The proxy caching system is only checking the if there is a cache for the Shopify store. This does not take into account other variables such as whether the access token has been changed. A great example is if the store removes your app access and decides to re-install the app at a later date. The access token would be different and therefore should also be checked during the getChachedAPI function.

I changed the function to also check to see if the cached access token is the same as the config access token.

if (!cached || Shopify._cachedAPIs[shop].access_token !== apiConfig.access_token) { cached = Shopify._cachedAPIs[shop] = new Shopify.API(apiConfig); }

This is an issue I have been dealing with for about a year and finally forked the package and found the fix.

Let me know if you need further explanation on why this should be implemented. Cheers
