Unsaved document tabs not restoring when global history setting is off

## Prerequisites
- [X] I have searched open and closed issues for duplicates.

## Describe the bug
If global history setting is off new unsaved documents tab not restored.

### To Reproduce
Steps to reproduce the behavior:
1. Disable global history from Privacy → History
2. Open Code editor
3. Create new document and close without saving
4. Reopen Code editor

### Expected behavior
I can understand respecting global "Privacy → History" setting here but for unsaved documents better to restore tabs.
