Updating course settings overwrites presentation score

[maximiliansoelch]

Describe the bug

When updating the general settings of a course, the presentation score defined in the grading scheme gets overwritten.
In the past, the presentation score was set in the course settings, but when it was moved to the grading schema, this was not properly handled and every save on the course settings now overwrites the score as it is not present in the settings' form data.

To Reproduce

1. Go to 'Scores' -> 'Grading Key'
2. Define a grading key and set a basic presentation mode and set the number to 2
3. Save the grading key
4. Go back to the course overview, click on edit
5. On the edit view click on save at the bottom
6. Go back to the grading key view and verify the presentation score has been overwritten

Expected behavior

When updating the course settings, the presentation score should not be overwritten
