Pocketmine-mp: Can't Join on Win10 Edition: Cannot write non-existing field "__encapsulatedPacket"

[Catboy96]

Issue description

When joining on Windows 10 Edition, PMMP got an error like this:

Could not execute completion of asynchronous task VerifyLoginTask: Cannot write non-existing field "__encapsulatedPacket"  
Error: "Cannot write non-existing field "__encapsulatedPacket"" (EXCEPTION) in "src/pocketmine/network/mcpe/protocol/DataPacket" at line 143

Windows 10 Edition can detect the PMMP server's information, like server name, players and ping status. But it cannot join.
I've tested on multiple Virtual Private Servers like DigitalOcean and Vultr and got the same issue.

• Expected result: Successully join PMMP server on Windows 10 Edition.
• Actual result: Could not join and got a server-side error.

Steps to reproduce the issue

1. Create a non-root account on Debian 9.
2. Do a clean install of PMMP on Debian 9 amd64 using 'https://get.pmmp.io' method.
3. Start the server using ./start.sh
4. Open Windows 10 Edition, enter server details and join.

guys, if all you're going to do is write "same", you might as well not bother. It's just a bunch of useless comments that a reader has to scroll through. Reactions are sufficient.
