An error icon can show on a successful migration in the plan details list view

[mturley]

This issue is coming up with the latest version of ManageIQ, because of this code:

taskDetails.completedSuccessfully =
    (task.options.progress && task.options.progress.current_description === 'Virtual machine migrated') ||
    (task.options.progress && task.options.progress.current_description === 'Mark source as migrated');

On a list item in the plan request details list, if the task is complete and its current_description is not one of those two magic values, there will be an error icon on the left of that list item. We need to instead check task.state === 'finished' && task.status === 'Ok', which we already use for determining a successful migration elsewhere in the code (we should just reuse the taskCompletedSuccessfully helper at the top of that same file)

This bug can be reproduced using the database dump named status-message-issues from my collection.
