feat: add lang parameter to the queriesPreview hash

[lauramargar]

Pull request template

When we made the implementation of cached the queries preview, we didn't realize that a queryPreview could work with different languages, but obtain different results.

Now when we change the language and a queryPreview return results in both languages we are not making a new request of the query with the new language. That's because the query is already saved in the state.

The change that we have made in this PR is to add the lang param to the QueryPreview hash.

Great job!
Maybe it makes sense to add a test to prove that the same query can be requested consecutively from 2 different langs without being cancelled?
