Fix "r" and "R" both replying with quote on inline comments

Summary: Ref T13513. The code which added "r" and "R" to the inline menu accidentally discarded the difference between the keystrokes.

Test Plan:
- Clicked an inline, pressed "r", got new empty inline (previously: inline with quote).
- Clicked an inline, pressed "R", got a new quoted inline.
- Repeated steps with the menu items, got the expected behaviors.

Maniphest Tasks: T13513
