severity vectors bug: Do not list ALL duplicated severity vectors in the UI. Also display the score

We should not list ALL duplicated severity vectors in the UI and we should display the score.
See https://public2.vulnerablecode.io/vulnerabilities/VCID-hh72-ne73-aaak

There is a list of 234 vectors!

We really have a handful of them:

> Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
> Vector: CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
> Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

1. This is a bug: `Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P`
2. We should not list vectors without a score and URL to the original reference, as this is devoid of meaning
3. We should list only unique vectors and a list of references
4. A free standing vector has no meaning in many cases. It is always attached to specific packaging.
