Empty property name delegates

[PerikiyoXD]

Input code

Having any delegate with stripped names (Using obfuscation methods)

internal delegate int SomeDelegate(string, string);

Let's have a look to the Invoke IL code:

.method public virtual 
	instance int32 Invoke (
		string '',
		string ''
	) runtime managed 
{
}

It uses empty named values, output is wrong.

Erroneous output

internal delegate int SomeDelegate(string, string);

Expected output

internal delegate int SomeDelegate(string P_0, string P_1);

I've added a quick fix, it shows proper code on this specific case. I can't provide the binary as it's private and sensitive.
