Title: Show message if placeholder course in student home page is still inconsistent during user interaction #1637

For Issue #1637

Added a message to evaluation submission if course is detected to be affected by eventual consistency:
"Updating of the course data on our servers is currently in progress and will be completed in a few minutes. Please wait a few minutes to submit the evaluation again."

Another message was added to viewing evaluations:
"Updating of the course data on our servers is currently in progress and will be completed in a few minutes. Please wait few minutes to view the evaluation again."

Example of how the message looks on staging server:
