Android-nRF-Mesh-Library: Crash app in sendBlockAck

Describe the bug When the library receives a segmented message that needs a block ack from an unknown node, the app will crash due to a NullPointerException.

To Reproduce Steps to reproduce the behavior:

provision two nodes to the network
manually delete one node from the database without sending a ConfigNodeReset
connect to the second node of this network
make the first node to send a message that makes the library to trigger block ack answer

Expected behavior Probably log some warning that the node is unknown instead of trying to send a block ack ?

Platform details:

Device: Any
OS: Android 8.0
Library Version 3.1.6

I gave this a test now and I am not able to reproduce this, I used the mesh chat example from the nRF Connect SDK where you can send a long message to a specific node. The fix from #461 have solved the issue in my humble opinion.
