v2: logging injected fields not in postcall log

[galexrt]

It seems that when injecting fields the fields are not in, e.g., PostCall, logs.

The reproduction for this seems to simply use InjectFields on a context and pass it on. The fields are in the newCtx but no the "original" ctx in the server.go.

Am I using InjectFields wrong or am I missing something else?

I'm noticing the same just using the example logrus logger, no fields being added, even with all the logging.Options configured.

The examples are wrong. They aren't iterating over the iterator.

instead of

if i.Next() {

it should be:

for i.Next() {

I'm also seeing the same with the zerolog example when using InjectFields to inject the subject from my JWT in my authentication interceptor function.

I can print the value fine via ExtractFields, but it's not output from the FinishCall event.
