Add null checks in Messaging task completions

Description

Provide details of the change, and generalize the change in the PR title above.

Add some null checks in the Android Task completion callbacks that finish Futures. Based on the callstack from https://github.com/firebase/firebase-unity-sdk/issues/1030, my guess is while there is a pending Android task, Messaging is getting cleaned up, and then when the Android task completes it does the callback, but the Future has been deleted.
