Some lists/tables do not clear after a student is created

[dondi]

In the new student page, the tables showing a student’s majors and minors do not clear properly after a student has been created. i.e., If a student is created with majors and minors entered, those majors and minors are “left over” when the page is cleared for the next student. The data here should go away, just like all the rest do.

britainjs will do this.

This has moved forward well, but with additional similar functionality for grades and food preferences, this issue now needs to be extended to those.
