Mapping links shown in wrong language

[osma]

At which URL did you encounter the problem?

http://finto.fi/allars/sv/page/Y41470

What steps will reproduce the problem?

1. Use Allärs with UI language (and content language) set to Swedish
2. Go to any concept page
3. Look at the mapping link to YSO/ALLFO

What is the expected output? What do you see instead?

Expected to see the target concept label in Swedish (the current content language) if it is available. But it is always shown in Finnish (probably because it's set as the default language of YSO).
