Set status for upload definition as non draft once the file processing has started

Currently, the uploadDefinition for which file processing has already in progress is marked as draft (uiStatus field) which makes it possible for it to be displayed on UI on the landing page, which may cause an edge case if the user decides to delete it and start over new uploading process. In this case, the server will return an error for delete attempt since the file processing has already started.

Things to change:
Change the status of uploadDefinition from draft status to the next when the file processing has started
Update API test to check uiStatus after jobExecution start
