Add a warning or an error message when setItem crash ?

[FVolral]

I've just spent several hours trying to understand a bug that was preventing me from persisting certain data in the indexedDB. I'm not sure if it's normal, but localForage seems to silently fail in the setItem function. However, I assure you that we would like to know if it crashed

We are seeing a similar issue. "Failed to execute 'put' on 'IDBObjectStore': [object Array] could not be cloned." This is despite wrapping in JSON.parse(JSON.stringify())
