Subject: [PATCH] emoji: Try to load emoji data using both language and
 territory

When loading the emoji data we just try to get the data for a language
while there may be territory specializations and emojibase provides
them.

So, split the loading function and try to load the data for the fully
defined language string (i.e. `it-ch`) before loading the generic one
for the language (i.e. `it`) and eventually falling back to the generic
english.
