problem

• open a task where source editing is enabled.
• sort the sourceEdit column
• close the task and open a task without source editing

The applying of the sort of the non existent column should produce the error in the linked TS-3650 issue - not verified yet.

solution

• Ignore / remove sorts and filters for non existent columns
• ensure that the sort /  filters are also updated in the user specific config for the grid
• ensure also that we don't have that problem with tasks with multiple targets
