Downloading asset only works with the 1st service, not others.

[FilipMasar]

Describe the bug
If asset has multiple services, the DownloadHandler works only with the first service. If I try to download asset after I buy e.g. 2nd service, I get Invalid service index. error.

To Reproduce
Steps to reproduce the behavior:

1. Publish asset with 2 download services (free or paid doesn't matter)
2. Buy/Get datatoken for 2nd service
3. Request the download url
4. See the error Invalid service index. in the file

Expected behavior
Get access to the asset.
