Michael Vetter 19de066008 Call ncurses resize function before move function 
From @xaizek s comment on issue #1235:
```
If the move would cause the window to be off the screen, it is an error and the window
is not moved.

Resize on the other hand doesn't fail like this according to its documentation. So new size needs to be applied first.
```

Big thanks to @xaizek for taking a look at our code and helping us!!
