Incorrect implementation of Creation extension

[richard-keller]

I've been trying to use tus-php to upload files to CloudFlare Stream. Eventually got it to work after much fiddling. Core to the problem seems to be that the tus-php client specifies its own upload filepath using the $key parameter, whereas this does not appear to be according to the protocol spec.

As per the Tus spec, on file creation, CloudFlare returns a Location header, which specifies the upload URL for the file. tus-php ignores this, and uses its own value of $key. This causes CloudFlare to fail the upload and return an internal server error.

When creating a new file, the server response is as follows:

HTTP/1.1 201 Created
Location: https://tus.example.org/files/24e533e02ec3bc40c387f1a0e460e216
Tus-Resumable: 1.0.0

The Location header should be the URL that is used for the PATCH request.
