Service extension methods should be cleared between app connections

[elliette]

The "registered methods for service" for hot restart are: [s0.hotRestart, hotRestart, hotRestart]

We call the first one which is s0.hotRestart, which is unrecognized. Calling just hotRestart is recognized however.

Code link:

devtools/packages/devtools_app/lib/src/service/service_manager.dart

Lines 170 to 175 in ddc8b5a

	final registered = _registeredMethodsForService[name] ?? const [];
	if (registered.isEmpty) {
	throw Exception('There are no registered methods for service "$name"');
	}
	return service!.callMethod(
	registered.first,

Ah this only happens if we have connect an existing DevTools to a new application. In this case I had DevTools connected to a macos app, I disconnected from that app, then I reconnected to a chrome app. The registered service extensions should be cleared when a new app is connected, otherwise we'll still be trying to use the old service extension names.
