Feedback permanent selections are not serialized

When user selects some option and mark it as 'do not ask again', the choice is remembered only until CH is closed.
The feedback state is not serialized and every time CH is opened, it starting as if nothing was selected.

Scenario:
1. Start copying something large (multiple files) to a location, where they already exist.
2. CH will ask to replace the files - select overwrite and mark it as 'do not ask again'.
3. Pause the task.
4. Restart CH
5. Resume the task.
CH will continue copying current file without asking (this is by design), but it will ask for overwriting at the next file. This is wrong. The second and next files should be overwritten as per user selection from before CH restart.
