All files that have a statement with deleted property `P727` fail to display, and show an error msg instead.

MediaWiki internal error.
Original exception: [Xo137QpAEKIAAIaUscAAAADY] 2020-04-08 07:06:21: Fatal exception of type "Wikibase\DataModel\Services\Lookup\PropertyDataTypeLookupException"
Exception caught inside exception handler.
Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.

Removing statements with the deleted property seems to fix the problem, see https://commons.wikimedia.org/wiki/File:Dr_Hjortons_Pulver,_Huskvarna.jpg (you can see from looking back through the revisions that it used to have statements with the deleted property)
