Dominik Sander 7d25b651fa Fix exception in AS::Timezone.all when any tzinfo data is missing ... 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 In our case the exception was triggered by an outdated tzdata package which did not include information for the "recently" added time zones.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 078421bacb `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.		2018-04-18 21:45:13 +02:00
