This allows users to use APIs that require booleans in query params not to be cast to int, e.g. `&foo=true`. Currently, `true` is cast to `1` so it's passed as `&foo=1`. That might not be supported by the target API.
The fix contains copy-pasted function from guzzlehttp/psr7 `Query::build()` with minor tweak.
