Don't archive preexisting archives if commandline is too long (#1140)

* Don't archive preexisting archives if commandline is too long

Fixes https://github.com/arduino-libraries/ArduinoIoTCloud/runs/1693000682?check_suite_focus=true#step:7:277
Should revert arduino-libraries/ArduinoIoTCloud#222

* Added test
