Fixes the saving pop-up to appear

[farhaanbukhsh]

When the user tries to add more than 5 grades then the save pop that appears near the footer doesn't appear.

JIRA tickets: Private ref: BB-9232

Testing instructions:

1. Set the theming as mentioned in Fixes the grade removing issues in studio. #72
2. Once that is done go to the grade page and see if you have more than 5 grades available.
3. If not you need to change settings under edx-platform

4. This should reload the LMS and if doesn't then you need to restart LMS by tutor dev restart lms
5. Hard refresh the page and try adding the grade and save the grades. More than 4 possibly.
6. Now try adding the grade again and you should see that the save grade box will not appear.
7. Now change to farhaan-grading-pop and restart the course-authoring app tutor dev restart course-authoring
8. Try the above steps again and you should see it working.

@farhaanbukhsh 👍

• I tested this: Verified that the save button issue is fixed as described.
• I read through the code
• I checked for accessibility issues
• Includes documentation

Note: Codecov is complaining about missing coverage. Also should we have an upstream PR for this?

@tecoholic it is related to openedx#1227 so I will just merge this with @xitij2000's branch
