Use ActiveJob UID for log initialization

[aapomm]

Summary

Refactor the job handling to use the ActiveJob UID instead. This requires the following changes:

• the controller will need to return the job ID
• create.js.erb will need to startup the ConsoleUpdater after receiving the job ID from the controller (callback)
• the job will not need the uid argument anymore
• In the upload controller, the inline call will need to be updated to call job.perform_now instead of calling the importer directly

Check List

• Added a CHANGELOG entry
