--server and --port startup params issue

Hmm, when I tested this (using --server localhost), my client crashed with

java.lang.NullPointerException: Tesselating block in world
	at dle.a(SourceFile:42)
	at dlc.a(SourceFile:60)
	at dne.b(SourceFile:214)
	at dnb.a(SourceFile:80)

	at cvi.d(SourceFile:954)
	at cvi.b(SourceFile:411)
	at net.minecraft.client.main.Main.main(SourceFile:154)

I attached the full crash report.

The same happened when trying to join another server that is actually a 1.13.2 server, but allows 1.14 players to join.

1.14.3-pre2 this issue not fixed.
