Subject: [PATCH] Create localization fallback (#17)

* Fix function call

get_email_from is a class function and should therefore be called like one.

* Create default localization

This will use en_US as a default fallback for localization in case the user has configured a language in roundcube where localization is missing.
This lead to empty emails without any confirmation code being sent.
