Wrong extraction of {{lang|text}} clauses

[s204451]

When input is in the format of {{lang|text}} in Wikipedia, dbpedia extracts nothing from within the braces.

Example:

https://dbpedia.org/page/Abruzzo
https://en.wikipedia.org/wiki/Abruzzo

native_name on wikipedia:

{{lang|nap|Abbrùzzu}} / {{native name|nap|Abbrùzze}}

Output on dbpedia (dbp:nativeName):

/

Expected output:

Abbrùzzu / Abbrùzze

Another example is https://en.wikipedia.org/wiki/Tokyo/https://dbpedia.org/page/Tokyo where native_name = {{Nihongo2|東京都}} is not extracted because it is evaluated to nothing.
