Description

Steps to replicate the issue (include links if applicable):

Find a user who's active on a sister project (not Meta/Commons/Wikidata), eg. Marek Mazurkiewicz, who's active on plwikinews
Open UserInfo card for this user (on any wiki)

What happens?:
Sister projects (in this case plwikinews) don't show up in "Active wikis" section. Only projects with database name ending with wiki show up.

If you open the card on a sister projects, the links to Wikipedias will lead to the respective language versions of the sister project (eg. on Wikinews, plwiki will be a link to pl.wikinews.org).

What should have happened instead?:
The sister projects should also be displayed.

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):

Other information (browser name/version, screenshots, etc.):

This problem is caused by CheckUserUserInfoCardService::getUserInfo, which should use WikiMap::getWiki to map database name into a wiki, instead of trying to map it onto an interwiki prefix.

Another symptom of this issue – projects in languages that end in i, k or w are incorrectly linked in the Active wikis section or absent from that section. For example:

mkwiki gets rtrimmed to m, which links to user contribs on Meta-Wiki, instead of Macedonian Wikipedia
newwiki gets rtrimmed to ne, which links to user contribs on Nepali Wikipedia, instead of Newari Wikipedia
tkwiki gets rtrimmed to t, which is an unrecognized interwiki target, so this entry will never show up
kiwiki gets rtrimmed to an empty string, which is an invalid interwiki target, so this entry will never show up
