Word "Nightly" appears instead of "Tor Browser" in a few places (12.0a4)

Word "Nightly" appears where it should say, and used to say, "Tor Browser" (12.0a4).

As in "About Nightly", "Hide Nightly", "Quit Nightly" and in the About Window, "Nightly is up to date". Also "Nightly support" in the Settings.

Seems like a minor mistake.
