fix uploadRemoteFile undefined (#4814)

* fix uploadRemoteFile undefined

for some reason, only when testing locally using VITE_COMPANION_URL=https://api2.transloadit.com/companion only
we get this error...
i'm thinking for some reason, the remote file gets serialized into state and then de-serialized again
causing remote.requestClient to be gone
so I solve it by instead storing the request clients in Uppy

fixes #4791

* fix bugs

* remove unrelated space changes

* apply suggestions

* Update Uppy.js

* fix lint
