Test Result failures following merge of !15

@totten @jaapjansma it would appear that the following test failures https://test.civicrm.org/job/CiviCRM-Ext-Matrix/BKPROF=max,CIVIVER=5.7,EXTKEY=org.civicoop.civirules,label=bknix-tmp/1030/ have been generated since the merge of !15 (merged). I note that this is happening across all CiviCRM versions that the Ext-Matrix tests on (5.7, master, 5.12, 5.11)
