Crash when repeatedly disposing and creating new Channel

[arthurbla]

Reproducable on Android device.
Repro: Create and dispose new channel until the app crashes.

In our game, we dispose the Channel on OnApplicationPause(true) and create it again on OnApplicationPause(false), just to avoid any possible connection problems that might arise. After repeatedly minimizing/maximizing the app, at some point it crashes. Happens both when GrpcChannel.DisposeHttpClient = true or when GrpcChannel.HttpHandler is reused.
