Duplicate ClassicActorSystemProvider binding when using with Play 2.8.3

[octonato]

Play 2.8.3 provides already a binding for akka.actor.ClassicActorSystemProvider which causes the following error:

A binding to akka.actor.ClassicActorSystemProvider was already configured at play.grpc.ClassicActorsystemProviderModule.<init>(ClassicActorsystemProviderModule.scala:13):
[error] Binding(interface akka.actor.ClassicActorSystemProvider to ProviderConstructionTarget(class play.api.libs.concurrent.ActorSystemProvider)) (via modules: com.google.inject.util.Modules$OverrideModule -> play.api.inject.guice.GuiceableModuleConversions$$anon$4).

Only affects Play users (Java and Scala) using Guice.

Workaround

Users upgrading to Play 2.8.3 can disable the play-grpc Guice module providing the binding with:

play.modules.disabled += "play.grpc.ClassicActorsystemProviderModule"

See PR #309

@octonato IIUC this is fixed, right? Can we close the issue already?

As far as I can tell the issue persists in Play 2.8.8/Play-grpc 1.1.1 when using guice
