Fix the malformed .catch callback.

packages/dev-server/src/server.ts:383 has invalid TypeScript syntax: catch is missing an argument expression, so the source does not compile. Pass the rejection value to the callback.

Proposed fix 
-            await exitedPromise.catch( => console.error());
+            await exitedPromise.catch((error) => console.error(error));

callback in the exitedPromise handling by declaring a parameter for the
rejection value, then preserve the existing console.error logging using that
value.
