This is a behavioural difference between request and got

request will send the request, then we'll get a
`400 Bad Request` back and re-throw at as invalid

got will pick up that the URL is invalid and throw
`RequestError: URI malformed` before attempting to send it
which we'll re-throw as inaccessible

Got doesn't natively support assmebling a querystring
from nested objects because it uses node's URLSearchParams
internally. Use qs and pass qs a string.

Wordpress is the only service that needs this,
so we could build the string manually in this case
if we don't want to take qs as a prod dependency.
It is mostly hard-coded values anyway.

got overwrites any ?foo=bar in the URL string if
searchParams is also passed whereas request appends
