Functions not working when passing empty list variable

[bloggy]

Description

Functions not working correctly when passing an empty list variable to them.

Steps to Reproduce

The script:

function testfunc(l: objects):
	broadcast "something"

command /testing [<text>] [<text>]:
	trigger:
		testfunc({_temp::*})

Result should be:
"something" in the chat.
But nothing happens. (not even a console error)

Now if you add an element to the list variable like this, it will work:

function testfunc(l: objects):
	broadcast "something"

command /testing [<text>] [<text>]:
	trigger:
		add "red" to {_temp::*}
		testfunc({_temp::*})

result: "something" in chat

Expected Behavior

The code in the functions should be executed, even when you pass an empty list variable to it.

Skript/src/main/java/ch/njol/skript/lang/function/Function.java

Lines 89 to 90 in 885a4b6

	if (params.length > 0 && params[0].length == 0) // Parameters exist, but parameters are not of the correct type
	return null;

Doesn't only apply for lists, it's basically anywhere the first parameter isn't set.
