Since, we didn't update `user_settings.color_scheme` for spectators
and our recipient bar color calculations were based on it, this
resulted in a wrong recipient bar color if the OS default color
scheme of the user was different from `spectator-theme-preference`
set by the user using the gear menu.
To reproduce the bug:
* Set preferred color scheme to `dark` in your OS settings / Chrome
dev tools.
* Login as spectator in Incognito.
* Switch to light theme.
You will see dark background colors in recipient bars.
