The models added in #17002 looks okay but they don't validate with the
errors:

m2m_through_regress.Event.people: (fields.E340) The field's intermediary
table 'm2m_through_regress_individualcompetitor' clashes with the table
name of 'm2m_through_regress.ProxiedIndividualCompetitor'.
m2m_through_regress.Event.special_people: (fields.E340) The field's
intermediary table 'm2m_through_regress_individualcompetitor' clashes with
the table name of 'm2m_through_regress.IndividualCompetitor'.
