Commit ready for merge. This commit implements fixes suggested by Henrik to the MeetingRegistration class

- added tests
    - reverted 'obj' to 'object'
    - removed check for valid email
    - identifing person by Email.person rather than Person.user__username
    - used a simpler form of unidecode logic.  TBD: the previous code was stolen from elsewhere in the code which should also be simplified.
    - Person.name now uses firstname + lastname rather than email.
 - Legacy-Id: 13969
