Notifications: ontology processing notification sends out misleading email about failed archived submission

[alexskr]

PR #184 and #148 restored new ontology submission processing notifications. When new submission is processed OntoPortal sends two notifications:
1 Success:

2: Failure for archived

Archive notification gets incorrectly flagged as a failure because archived submission is no longer ready. The second notification about archived submission should not be send out because it might confuse users and I don't think users are interested in getting that information in the first place.

Here is a commit that we did at Agroportal to fix that agroportal@6af858a

You can copy the fix if it is good for you

Thanks @syphax-bouazzouni, 602a44c fixed the issue
with the notifications about archived submissions.
However, do users even need to know that the previous submission was archived?
