[Reactive] CommandAttribute(isEnabled=false) not stored anywhere

[weitzhandler]

Current behavior

The CommandAttribute class reads:

[AttributeUsage(AttributeTargets.Method)]
public class CommandAttribute : Attribute
{
    public CommandAttribute(bool isEnabled = true)
    {
    }
}

Expected behavior

The parameter isEnabled should be stored.

Also, inspecting the code here

It seems it only checks if a method has this attribute completely ignoring its value.
Furthermore, if this attribute exists and its value is false, it should exit the if statement and opt-out of command generation for this method as it's been explicitly excluded.

I'm happy to PR.

Seems this functionality works well. I also learned that those properties are not required.
Anyway, I added a test case that checks the reverse behavior of disabled implicit class and explicitly enabled method.
#1483.

So does the current behaviour mean that [Command(false)] doesn't work to opt out of command creation?
