Title: ref #7245 Inconsistent output from ActiveSupport::TimeZone.all

Now this is not given any inconsistent out. This is my first commit.

ActiveSupport::TimeZone.all
# not in ActiveSupport::TimeZone::MAPPING, but still a valid zone
chicago = ActiveSupport::TimeZone['America/Chicago']
ActiveSupport::TimeZone.all.include?(chicago)
=> false

chicago = ActiveSupport::TimeZone['America/Chicago']
ActiveSupport::TimeZone.all.include?(chicago)
=> false
