Xpra: Ticket #1859: --use-display: XAUTHORITY is not honoured

System: debian 9, winswitch repository

Since xpra v2.3-r19246 xpra does not use/regard XAUTHORITY to access a display with --use-display if the specified display uses cookie authentication. It fails with 'no protocol specified'.

Code to reproduce:

/usr/bin/Xvfb :40 -screen 0 1920x1080x24 \
  -nolisten tcp -dpms -s off -retro \
  +extension Composite +extension RANDR +extension RENDER +extension GLX\
  +extension XTEST \
  -auth /tmp/cookie \
  &
sleep 2
xauth -f /tmp/cookie add :40 . $(mcookie)
# env DISPLAY=:40 XAUTHORITY=/tmp/cookie xterm   #no error message
env DISPLAY=:40 XAUTHORITY=/tmp/cookie xpra start :40 --use-display  --start-via-proxy=no --daemon=no
