Form Attachment Issues

- Make sure we keep attachments in the session even if the page refreshes to display an error message
- Reverse the array of files to be id => name instead of name => id
- Make sure we retain the old ticket or task id if we encounter an error while trying to create a ticket or task from a thread entry
- Make sure we have a valid fileId before returning file info
- Make sure we can still add files for Canned Responses (id and name flip issue)
- Make sure we can still add attachments to Internal Notes for Tickets and Tasks
