Reorganized changes in the duplicates related liquibase files. The files in folder 2019.2.1 have been reset to the version before the change from commit 50be8ae4 which is the same as in 2019.3.1.
Those changes have been moved to drop and alter liquibase scripts inside the folder 2019.3.2/Duplicates. Now an update from 2019.3.1 -> 2019.3.2 creates the correct liquibase structure.
