Some Jenkins jobs now fail for all changes to Wikibase. E.g. https://gerrit.wikimedia.org/r/#/c/270008/ and https://gerrit.wikimedia.org/r/#/c/270572/. Errors I see:
11:28:52 PHP Strict standards: Declaration of Capiunto\Test\BasicRowTest::testLua() should be compatible with Scribunto_LuaEngineTestBase::testLua($key, $testName, $expected) in /mnt/jenkins-workspace/workspace/mwext-testextension-php55-composer/src/extensions/Capiunto/tests/phpunit/output/BasicRowTest.php on line 51
11:39:14 1) LuaSandbox: Wikibase\Client\Tests\DataAccess\Scribunto\Scribunto_LuaWikibaseEntityLibraryTest::testRegister 11:39:14 Failed asserting that LuaSandboxFunction Object () is an instance of class "Scribunto_LuaStandaloneInterpreterFunction".
I guess some change to Scribunto broke compatibility...
