Changing rake db:schema:dump to run :environment as well as :load_config, as running :load_config alone will lead to the dumper being run without including extensions such as those included in foreigner and spatial_adapter.

This reverses a change made here: 5df72a238e (L0L324)

I'm assuming here that :load_config needs to be invoked separately from :environment, as it is elsewhere in the file for db operations, if not the alternative is to go back to "task :dump => :environment do".
