When shares are accessed via user API calls and the users linked to these shares are no longer available,
the shares become inaccessible to external users.

Definition:
Access → Jira user account has no access to Jira or account was deleted or maybe some other cases??

We can provide in project configuration an option to automatically select new share actor
if previous share actor lost access to Jira instance.

Can we detect this upon share render?
If yes and we detect that share owner lost access we should change share actor to the one from project configuration.
