🐛 Fixed error when importing members

fixes TryGhost/Team#2266

The getCreatedEvents method was removed but was still used in the verification trigger. This commit adds the method again as a quick fix. A better fix will be commited later: https://github.com/TryGhost/Ghost/pull/15831, which includes tests that also have been ran on this change (but keeping it out of this commit to keep changes minimal).
