An error occurs when we're trying to remove a predecessor link using the undo functionality.
Steps to reproduce on the Advanced gantt example:
- Create 3 tasks A, B, C each connected through a Finish to Start Dependency
- Add 'A' as the predecessor of 'C' using the column (eg: 1;2)
- Hit 'Undo'
Uncaught (in promise) TypeError: Cannot set property from of [object Object] which has only a getter
