Object function parameter with a text default value causes severe error

[ItzAtomikHD]

Description

If you create a function with a parameter of type object and you want to give it a default value of a string, it causes an error.

Steps to Reproduce

Create a function with a parameter type object and a default value of a string.

function blah(s: object = "") :: text:
	return "%{_s}%"
	
command /test:
	trigger:
		set {_default} to blah()
		set {_custom} to blah("hey")
		broadcast {_default}
		broadcast {_custom}

Expected Behavior

The default value to be applied when no parameter is passed.

Errors / Screenshots

An error is thrown from Skript, but only when no parameter is passed.

Server Information

• Server version/platform: Spigot 1.14.4-R0.1-SNAPSHOT
• Skript version: 2.4-beta5

This is because the object specified as a default value must be serialized to an actual string before. They fixed it for function parameters but not for default values like this.

This breaks a realistic use case of functions.
