fix: crash when using searchParams option

[sk-gachou]

This pull attempt to fix the issue when trying to use searchParams option for http client.

According to the doc, one can provide searchParams (an URLSearchParams instance) to add extra query parameters. Currently, this behaviour does not work, see this gist: https://gist.github.com/sk-gachou/2dd253acb1e1663e37119120c2db4768

It crash at this line: https://github.com/ipfs/js-ipfs/blob/master/packages/ipfs-http-client/src/lib/to-url-search-params.js#L42
