Title: strip processed fields in instructor dash

This PR strips leading and trailing whitespace from fields in the instructor dash. Previously, when instructors would accidentally type in " foobar" instead of "foobar", a confusing message would pop up, saying something like 'could not find student with username " foobar" '
