When uploading a file, we previously made a check on whether it
supported both `#read` and `#path` before wrapping it in a
`Faraday::UploadIO` and sending it off. The second check on `#path`
isn't strictly necessary, and as reported in #761 can prevent objects
created by `open-uri` from being compatible with file upload.
Here we remove the check `#path` so that we just require that objects
support `#read`, and in addition error when an object is passed that's
not file-compatible and not a string. This should prevent users from
seeing the very confusing "Invalid hash" error in these situations.
Fixes#761.
