LOG: Revert "[Assignment Tracking][5.1/*] Add deleteAssignmentMarkers function"
This reverts commit 4c44fa1c3829c2d0c6ce10b576dafbc2e0631d47.
This patch has to be reverted because I need to revert 171f7024cc82e8702abebdedb699d37b50574be7 and without reverting this patch, reverting 171f7024cc82e8702abebdedb699d37b50574be7 causes conflicts.
Patch 171f7024cc82e8702abebdedb699d37b50574be7 introduced a cyclic dependency in the module build.
