[BUG REPORT] WrapperPlayServerMultiBlockChange causes players to be kicked

[XReioX]

Describe the bug So when you read a multiblockchange packet, it will kick you with EncoderException: NPE

To Reproduce Steps to reproduce the behavior:

1. Start up a 1.8.8 server
2. Log into 1.8.8 server with a 1.8.9 client
3. Have a plugin ready what is reading the multiblockchange wrapper
4. Just log in, and walk around and try breaking block etc

Expected behavior I expect that it will not kick me, and instead give me the data requested.

Screenshots None
