Alex Vandiver c2e0a27d2c upload: Fix uploading the same file twice in the same session. ...

This commit fixes a bug where uploading the same file a second time
in the same browser session would appear to the user to stall with
`Uploading [filename]...` in the composebox.  This is because
`tus-js-client` makes a HEAD request to check for already-uploaded
files -- and, if found, that request is used in the `upload-success`
callback.  That left the callback with no response body to parse, to
know what URL to insert.

Store the `/user_uploads/...` URL in the file metadata after a
successful upload, and if the fingerprint matches a previous upload,
pull that URL (and filename, as it may have changed server-side) out
of the previous upload's metadata.
