Score inconsistency between the emails list and the email panel

[Flaburgan]

Describe the bug
I have an inconsistency between the SpamScore column in the e-mails list which displays a score of 607 and the button in the email visualisation which displays a score of 20.

When I looked in the email header, I see that there are two scores provided:

Organization: OVHcloud
User-Agent: OVHcloud nces
X-Mailer: OVHcloud nces
X-Ovh-Nic: zi25062-ovh
X-Ovh-Notification-Id: [TOO LONG, REMOVED]
X-Ovh-Template: nic/de/newNicEmailValidationCode2020v1
X-Ovh-Tracer-Id: 11871770093883736351
X-VR-SPAMSTATE: ACCOUNT
X-VR-SPAMSCORE: 20
X-VR-SPAMCAUSE: [TOO LONG, REMOVED]
X-Ovh-Spam-Status: OK
X-Ovh-Spam-Reason: vr: ACCOUNT; dkim: disabled; spf: disabled
X-Ovh-Message-Type: ACCOUNT
Message-ID: <a8e60e9a-81da-4441-89bf-9b8e9a05f914@notification-center-email-sender>
X-OVH-Remote: 136.55.171.214 ([136.55.171.214])
X-VR-SPAMSTATE: PHISHING
X-VR-SPAMSCORE: 607
X-VR-SPAMCAUSE: dmFkZTFq0UdeaoNjrzVJDj[TOO LONG, REMOVED]
X-Ovh-Spam-Status: OK
X-Ovh-Spam-Reason: vr: ACCOUNT; dkim: disabled; spf: disabled
X-Ovh-Message-Type: ACCOUNT

So it looks like the addon is in one case stopping at the first X-VR-SPAMSCORE it is encountering, and in the second case at the last one. The same logic should be used in both places (I guess always the last one? in that case that is the correct score).

Idk why OVH is sending two X-VR-SPAMSCORE, but in that specific example, the e-mail definitely is a phishing tentative, so I would say that this addon could be a bit smarter and look for X-VR-SPAMSTATE and if it is PHISHING then this score should be the one chosen.
