wrong error from curses.wrapper if curses initialization fails

One way to reproduce is trying under IDLE.app in OS X:

  import curses
  def scr(a):
    a.getch()

  curses.wrapper(scr)

Traceback before patch:
  UnboundLocalError: local variable 'stdscr' referenced before 
assignment

Traceback after patch:
  _curses.error: setupterm: could not find terminal

APPLIES         2.6, 2.7, 3.0, 3.1
