[ tool ] Don't throw StateError when DDS fails to start (#158744)

Browse Source 
This started happening after moving DDS to launch from `dart
development-service` rather than `DartDevelopmentService` (see
33b402d24c) . This state error was
originally meant to be thrown when some string parsing failed, but is
currently wrapping the `DartDevelopmentServiceException`.

Fixes https://github.com/flutter/flutter/issues/158537
