The logic in the code was deliberately avoiding index `2` (**Selected
Font**; the debug font) by using `std::min(index, 1)`. Presumably, the
reason was that there was no debugger in Qt version of Dolphin at the
time.
Test plan:
- Select a debug font via the **Options > Font...** action.
- Show the **Log** tab via the **View > Log** action.
- In the **Log** tab, choose the **Selected Font** item in the combobox.
- Restart Dolphin.
**Without** the patch, the **Monospaced Font** item is wrongly selected
in the combobox.
**With** the patch, the **Selected Font** item is now properly restored
from the saved settings, and the selected debug font is correctly used
in the log messages.
