Rework form helper example to use Person.new
Rework form helper example to use Person.new

The previous change 92a3c8dcdf174dab5e8759031b6bbe6cd891fe3c improved
this example, but calling .create + #valid? ends up running validations
twice, and we don't want to showcase that.

Lets use the normal use case of building a new object and calling #save
on it, which is what a basic scaffold with Active Record does.
