When attempting to generate a Finnish ssn of a certain age the provider crashes because datetime.timedelta(days=self.generator.random.randrange(min_age * 365, max_age * 365)) is always trying to generate a time within range. The ssn provider should handle situations where min_age and max_age are the same.
For example:

if min_age == max_age:
    age = datetime.timedelta(days=min_age * 365)
else:
    age = datetime.timedelta(days=self.generator.random.randrange(min_age * 365, max_age * 365))

Steps to reproduce

1. Create a faker with fi_FI locale: fake = Faker('fi_FI')
2. Call the ssn provider with the same minimum and maximum age: fake.ssn(min_age=50, max_age=50, artificial=True)

Expected behavior

The faker generates an artificial Finnish ssn that is 50 years old.

Actual behavior

ValueError: empty range for randrange() (18250, 18250, 0)
