[mediawiki/extensions/Wikibase@master] Fail Special:SetAliases and Special:SetLabelDescriptionAliases with aliases containing | character

https://gerrit.wikimedia.org/r/510215

+++ Steps to verify +++

Prerequisits:

• Mediawiki Docker setup (or access to log files in other setup)
• LocalSettings.php includes a path to your log file like so: $wgDebugLogFile = "/var/log/mediawiki/debug.log";

1. Start your containers
2. Through the js editing layer add an alias with pipes to an exisitng item
3. then got to SetAliases through the special page (in my case it looks like this: http://default.web.mw.localhost:8080/mediawiki/index.php?title=Special:SetAliases/Q180)
4. try to save the alias using the set aliases button -> an error message appears
5. Enter the container in the mw docker directory, ./bash
6. navigate to the path where your log ffile lies and type: tail -f debug.log | grep SetAliases

You should see a log message indicating there was a save attempt for aliases with pipes.
(points 3-6 could be repeated for Special:SetLabelDescriptionAliases)

It now should be testable in beta cluster, right?

of course #facepalm . How do we check logs on Beta cluster?
