Usage with gem tolk

[jhovad]

I know it's not an issue directly of spree_i18n, but I think it's more related to this one than to tolk ... And I think tolk is so handy, it's nice to have the possibility to integrate.

The problematic parts from tolk:
https://github.com/tolk/tolk/blob/9c6fc6cd23c467049f97a613617e4bd0ac3fdde6/lib/tolk/sync.rb#L15
-> raise:
NoMethodError: undefined method `initialized?' for #I18n::Backend::I18nDataBackend:0x00007faa7e1b7670

https://github.com/tolk/tolk/blob/9c6fc6cd23c467049f97a613617e4bd0ac3fdde6/lib/tolk/sync.rb#L28
-> raise:
NotImplementedError: NotImplementedError
/Users/josef/Documents/Develop/bellinda-spree/vendor/tolk/lib/tolk/sync.rb:29:in `load_translations'

I suspect that those methods (initialized?, load_translations) should be included here from Base:

spree_i18n/config/initializers/country_names.rb

Line 7 in 71cf9de

include Base, Flatten

Anyway ... I have no clue how to fix it. :-(

In case you consider it's more tolk issue, it's also very valuable information.
