Span completer never shuts down

[soujiro32167]

I've got an integration test that runs a web app with NewrelicSpanCompleter.

It never shuts down after upgrading to v0.14.1:

Scala 2.13.10
JDK 17

import cats.effect.{ExitCode, IO, IOApp, Resource}
import org.http4s.jdkhttpclient.JdkHttpClient
import trace4cats.model.TraceProcess
import trace4cats.newrelic.{Endpoint, NewRelicSpanCompleter}
import trace4cats.{EntryPoint, SpanSampler}

object catstracing extends IOApp {
    val app = for {
      client <- Resource.eval(JdkHttpClient.simple[IO])
      completer <- NewRelicSpanCompleter[IO](client, TraceProcess("foo"), "???", Endpoint.US)
      ep = EntryPoint[IO](SpanSampler.always[IO], completer)
      root <- ep.root("root span")
    } yield root

    override def run(args: List[String]): IO[ExitCode] =
      app.use(root => IO.println(root.context)).as(ExitCode.Success)
}

If I run it as a fiber, its impossible to interrupt either...

@soujiro32167 could you retest with the 0.14.7 version? There were some fixes to the span completer internals that could have resolved this since you opened this issue.
