Fix deploy

[bchamagne]

Yesterday's commit introduced a regression and we could not upload folder anymore:

[bastien@T495 aeweb-cli]$ ./aeweb.js deploy --endpoint http://127.0.0.1:4000 --seed bastien --path ~/Chamagne/archethic/archethic-website/
Connecting to http://127.0.0.1:4000
Creating file structure and compress content...
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received an instance of Object

This fixes it
