Describe the bug

When letting faker generate email addresses based on names, it now generates invalid email addresses, where older versions did not.

Example:

# Faker 3.4.1
Faker::Internet.unique.email(name: " Msgr. Titus Harvey")
# => "harvey.msgr..titus@russel-von.example"

The email is invalid as two sequential dots appear.

# Faker 3.3.1
Faker::Internet.unique.email(name: " Msgr. Titus Harvey")
# => "harvey_msgr_titus@corwin.example"

To Reproduce

See code samples above

Expected behavior

Factory should keep generating valid email addresses, as a major escape is to populate databases with valid looking data.
