before chronojump-importer show persons that are going to be imported and decide issues
When showing tests that are going to be imported, show persons. This way we could know if a person already exists in db and decide.
Because Chronojump cannot have a user named prova and another named Prova. But importer incorrectly creates the Prova user, and then when we want to edit ther weight of this person it says that prova already exists
This way we can decide with radio buttons if new person is the same than person in DB and what name use. Or give a diff name to new incoming person.
