When the server fails to start up (writing to stderr) the tests currently would just hang waiting for responses to messages. This will just throw the message as an exception, failing the test with a more useful message, for example:
```
00:07 +0 -1: ServerTest | test_exit_afterShutdown [E]
Analysis Server wrote to stderr:
file:///Users/dantup/Dev/Google/dart-sdk/sdk/third_party/pkg/linter/lib/src/analyzer.dart:106:27: Error: The method 'registerDefault' isn't defined for the class 'Registry'.
- 'Registry' is from 'package:analyzer/src/lint/registry.dart' ('file:///Users/dantup/Dev/Google/dart-sdk/sdk/pkg/analyzer/lib/src/lint/registry.dart').
Try correcting the name to the name of an existing method, or defining a method named 'registerDefault'.
Registry.ruleRegistry.registerDefault(lint);

Otherwise we'll need to increase the timeout to account for server startup (which will mask if the exit really is taking a longer time than it should).

This tests we can spawn the diagnostic server on-demand. The test was previously marked failing because it needed to be a real inrtegration test.

This adds a new server state "shutting down" which rejects requests. The LSP spec says clients should send the shutdown notification, then the exit notification. If an exit notification is received without a shutdown, then the exit code is set to 1.
