Description
Describe the bug
Arduino-ide can leave behind something listening on port 50051 if the gui exits uncleanly

To Reproduce
Steps to reproduce the behavior:
- in a terminal
/path/to/arduino-ide 2>&1 | tee /tmp/arduino-log-1 - get annoyed at how long startup takes
- kill the process with
^C /path/to/arduino-ide 2>&1 | tee /tmp/arduino-log-2- observe the listen failure
Expected behavior
Either clean up all processes on the way out, or try to reuse existing arduino-cli process
