Upgrade step for cleaning refences + detect and fix duplicates (!23) · Merge requests · mantisbt / EmailReporting

Kirill requested to merge github/fork/cproensa/upgrade_clean_refences into master Nov 26, 2016

Created by: cproensa

Adding the clean up step for config upgrade.

Also: Regarding avoiding duplicated references, this is my approach after discussion in https://www.mantisbt.org/bugs/view.php?id=21850 Note that the duplicated references scenario can also happen when bugs are deleted externally, bypassing the delete event. The approach here: first cleans up the duplicates, and then insert the correct one for the current bug.
