Matt Lott 6f08d5e422 Add required district field to teacher trial request forms
School now optional
N/A placeholder on district field and don't save it if it's n/a
Updating required field error UI a bit, and there is some larger
refactoring needed here later.
NCES phone number for district only entries will currently be a child
school, will fix later.
