Snackbar incorrectly reports that it is leaving port connected. #347
Description
Loading the default profile while not connected to serial port results in snackbar incorrectly reporting that it is leaving port connected. The snack bar message is:
Profile "Default profile" loaded.
Already connected port matches one specified in profile. Leaving port connected.
This is probably because the last serial port is "" and the default is "". It probably needs to check to make sure the port is connected before reporting that message.
