Fix DioErrorLog in the TalkerDioLogger

[raspberry-jenshen]

Describe the bug
If we use TalkerDioLogger it produces DioErrorLog once the request fails.

But the parent TalkerLog fields are empty.

It produces issues because you can't use the TalkerLog abstraction; you need to cast it to DioErrorLog to log it properly.

To Reproduce
Steps to reproduce the behavior:

// setup Interceptor
final _developmentNetworkLoggerInterceptor = TalkerDioLogger(
  talker: talker,
  settings: const TalkerDioLoggerSettings(
    printRequestHeaders: true,
    printResponseHeaders: true,
  ),
);

2. Fail Network call
3. See the log in the debugger.

Expected behavior
Fields: logLevel, exception, stackTrace. are not null
