gh-154751: Fix use-after-free in curses.initscr() after newterm() (GH-154752)

initscr() called while a newterm() screen is current returned a second
window object over that screen's standard window, with no reference to
the screen.  Either wrapper could then free the window used by the other.

Return the screen's own standard window instead.
