This just fixes an issue when running either ./bin/setup.sh -Dg or ./bin/regen.sh where a warning would be displayed in PHP7.2

@seamuslee001 this looks more correct with your change.

However, I get a small style regression after running GenCode after applying it

diff --git a/CRM/Core/I18n/SchemaStructure.php b/CRM/Core/I18n/SchemaStructure.php

@eileenmcnaughton just pushing a fix for that now i think, not sure how this function ever actually worked sensibly

@seamuslee001 agree this results in no change. Adding merge on pass but I'm not sure what to make of the test fails

Jenkins re test this please
