_Objective_
As a DC user, after uploading a document to DC, I need to be fully informed of any additional processing taking place on my document that could impede my current task.

_History_
With the introduction of decoupling entity extraction from document imports, documents are first imported, and then a background job is started to begin entity extraction. Today, after a document has imported the document appears to be complete, even if the entity extraction job is still running.

_Successful test case_
After a user uploads a document and the initial import completes, if the user attempts to clicked "View Entities" on a document that is still undergoing entity extraction, the user should be informed: "We're still extracting entities from your document. Check back in a little while."

_Technical Change Overview_

• Update API to include jobs being processed in the response of GET /document/:id
• Add error message (also localized) to constants
• When clicking the action "View Entities" ensure all dependent jobs have completed.
