Security::Finding#remediations raises an exception if the artifact file is removed

Why are we doing this work

Artifacts can be removed from the system either manually or by a cronjob once they are expired. If the artifact is removed from the system, trying to access the remediations of the findings related to that removed artifact raises an exception as the logic can not find the file. We need to fix this error.
