Memory leak problem after fetch() using firebase remote config sdk.

Hi there.
I’m using the firebase remote config lib in my app.

I found a memory leak problem as shown below screenshot during testing app.
The leak is found when I trying fetch method in remote config sdk.

My develop environment :

• Xcode 9.4.1
• Firebase (5.4.0)
• FirebaseRemoteConfig (3.0.0)

This is fixed internally and will be out in the next ABTesting release. For the curious, we weren't invalidating our NSURLSessions.

Internal patch number cr/204376974
