Different settings page are launched for Tor window

[simonhong]

Description

Tor window opens different settings page depends on how user opens settings page.
With app menu in Tor window, Normal profile's settings page is opened.
With shortcut(ex, cmd + ,), Tor profile's settings page is opened.
I think Tor window always should use normal profile's settings page instead of its own because Tor window is based on private profile. cc: @darkdh @yrliou

Steps to Reproduce

1. Launch browser and open Tor window
2. In Tor's NTP, open settings page via app menu
3. Check normal profile's settings page is opened
4. In Tor's NTP, open settings page via app shortcut
5. Check different settings page is opened

Actual result:

Different settings page are opened.

Expected result:
