[flutter_tools] Fix missing stack trace from daemon (#144113)

Browse Source 
When the daemon throws an exception, the receiving client is unable to surface stack traces from the daemon.

This is because it is sent with the `trace` key here:

1e8dd1e4d6/packages/flutter_tools/lib/src/daemon.dart (L308)

But the client tries to read it with the `stackTrace` key here:

1e8dd1e4d6/packages/flutter_tools/lib/src/daemon.dart (L343)

Thanks to @mraleph for spotting this!
