Inconsistency other_titles output

[Ratan Dhawtal]

Empty other_titles are null on the record APIs (/anime/ and /manga/) but empty arrays on the list APIs, they should always be the same type.

For API 2 we could use maybe this solution: other_titles should be null in the list APIs as it is always empty and the record APIs return objects (instead of arrays).

After reproducing the issue I found out that it didn't existed.

This has been tested with: http://myanimelist.net/anime/48 & http://myanimelist.net/animelist/ratan12.
