chore: use .create function for http client and ipfs client

ipfs/js-ipfs#3550 switches away from default exports for `ipfs-http-client`
and `ipfs-client` to enable an easier transition to es6 modules.

All `ipfs` modules now export a `.create` factory function which returns
instances of the client module.

BREAKING CHANGE: expects `ipfs-http-client` and `ipfs-client` to export a `.create` function
