When clicking Send Queue in Confluence, use the queue's user
2 changes in this issue:
We used the current, admin user when sending the queue, in the Confluence administration. It isn't good, because the admin can't see the potential errors. We'll use the queue user now, with impersonation. I have checked, and it displays errors such as the user being anonymous in Jira, which didn't display before.
Log the username used for the connection to Jira. When the Jira authentication fails, remind the user which user was used.
