[i18n] Fix set_language error with empty lang string

Browse source 
The Web server config for language was set to an empty string which
resulted in an warning logged by i18n set_language.

* Changed set_language to ignore empty language string and do nothing.
We don't want to override the user's system language unless actually
specified by the user.
* Improved the translation warning message.
