Before this change missing timezone data for any of the time zones defined in `ActiveSupport::Timezone::MAPPING` caused a `comparison of NilClass with ActiveSupport::TimeZone failed` exception. Attempting to get a timezone by passing a number/duration to `[]` or calling `all` directly will try to sort sort the values of `zones_map`. Those values are initialized by the return value of `create(zonename)` which returns `nil` if `TZInfo` is unable to find the timezone information. In our case the exception was triggered by an outdated tzdata package which did not include information for the "recently" added time zones. Before 078421bacba178eac6a8e607b16f3f4511c5d72f `zones_map` only returned the information that have been loaded into `@lazy_zone_map` which ignored time zones for which the data could not be loaded, this change restores the previous behaviour.
