Reload preview should be active when status Previewing
Based on the statuses and actions spreadsheet, when a book component is in status 'Previewing' we should be able to click 'reload preview'.
This works fine when you upload the source file, submit it and get the previewing status.
But not in the following scenario:
- Upload source file
- Go to files tab and upload converted file
- Click reload preview
- Status is updated to previewing. At this point the reload preview should be active.
