If a Wikipediareferens contains a : in the article part, the link we generate in the place bubble becomes incorrect.

For an example, search for "Sankt Eriksplan" and select the metro station (the train symbol in the list).
The Wikipedia referense in this example is: sv:S:t Eriksplan

Looking at the code, in placeBubble.js:106 it's obvious it splits the string on : and only takes out the first two parts to contruct an https://<lang>.wikipedia.org/wiki/<article> linke, which in this case only gets "S" as the article part, so it should probably re-join the array parts after [0] instead of just taking parts[1].
