Need a fix similar to flutter/flutter-intellij#4633. In flutter/flutter#57590 Flutter started using \r without \n and we fail to treat it as a newline. This means if the daemon starts up and gets "Waiting for another Flutter process to release the lock" the next line (usually the daemon.connected event) isn't handled correctly, and therefore we never enabled device scanning.

To repro:

• Delete flutter_tools.snapshot
• Run flutter doctor in a terminal
• While doctor is running, open a Flutter project
• Note status bar always says "No Device" even after the daemon starts up
