Reported by @Zippybonzo on Discord

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

• https://quarry.wmcloud.org/
• New query
• In the database text box, type "enwikip", then view the suggestions it gives

What happens?:

• It suggests "enwikipedia", which is an invalid database

What should have happened instead?:

• It does not suggest invalid databases. "enwiki" is the correct database here, I think

Software version (skip for WMF-hosted wikis like Wikipedia):

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

• Is enwiki_p obsolete now? Maybe *_p databases should also be removed
