init_ws_for_output: use workspace_move_to_output
4d21f4c 
This fixes a crash produced with the following config:
    # i3 config file (v4)
    workspace 1 output $screen1
    workspace 2 output $screen2

    exec --no-startup-id "i3-msg workspace 1, open && i3-msg workspace 2 && xrandr --output $screen2 --off && xrandr --output $screen1 --auto --output $screen2 --auto --right-of $screen1 "

Which results in:
ERROR: AddressSanitizer: heap-use-after-free on address …
