Tests

I tested this PR by doing the following (tick all that apply):

• [x] Writing PHPUnit tests (commit these in the tests/phpunit folder)
• [x] Playtesting using a Minecraft client (provide screenshots or a video)

the only problem left is that the re-generated actual-problems.neon removes following thing:

		-
			message: "#^Parameter \\#1 \\$logFile of class pocketmine\\\\utils\\\\MainLogger constructor expects string, string\\|false given\\.$#"
			count: 1
			path: ../../phpunit/scheduler/AsyncPoolTest.php

Should I just copy & paste it in the file? lol

Is this pr finished or is something left? I ask because of the Label

[pandaaaBE]

Should be ready for a final review

Any idea how to resolve this conflicts?
