files-api: join base-url and upload-url

[HMEiding]

Description

On Private Link projects, the "uploadUrl" does not contain the netloc portion of the URL. Updating FilesAPI.upload_from_bytes() so that the "uploadUrl" is joined with self._config.base_url whenever the netloc portion is missing.

I added two unit tests.
