[Gradebook] Remove the grade sync error for scores that have being removed
This year we have been experiencing an error message for many instructors that may have mistakenly given the wrong student a grade and then remove it. When the instructors go to sync, they get a vague error message "This is caused by a score being entered for an assignment and then that score being removed. This error should not prevent other grades from processing normally and should resolve itself once a new score is entered in Canvas.", but it doesn't show which assignment or student this impacts so they can resolve the issue. If an instructor has done this with multiple assignments and teachers, this will require a support call to resolve.
Since having a blank score does not impact a grade sync, removing a grade should not as well. Please remove this error protocol or update it to contain more precise troubleshooting details.
