Check if params of the Query is serizlized before key generation

[igorkamyshev]

Some tech debt was introduced in #131 🙃

Let's imagine:

const query = createQuery({ handler: (p) => null })

cache(query)

const someUnserializableData = /* ... */

query.start(someUnserializableData)

JSON.stringify(someUnserializableData) would be used as a part of a key, in some cases it could be unusful.
