`--non-interactive` not working correctly

[MabezDev]

I'm trying to debug save-image_write-bin.sh test for #901, but I noticed that even if I supply --chip espflash still tries to open a port selection dialogue. Even worse, it tries to open it but fails because of the --non-interactive flag, which is bad because I'm literally in a terminal that can do the dialogue.
