- Fixes `CachePersistor`'s `getSize` function when serialize is `false`.

return new Promise(resolve => {
if (this.storage.size === 0) return resolve(0);
const data = this.storage.get(key);
resolve((typeof data === 'string' ? data : JSON.stringify(data)).length);

Worried about performance implication of serialization just for size limitation.
Typically when using non strings clients data can be very large (like in index db)
I would be reluctant to merge it.

Maybe something like Object.keys(data).length could work?

I think that would require another sizeFunction argument to be passed by user then default one would simply use string length function
