fix(agama): re-engineer how calls are working in the engine

[jgomer2001]

Case 1. Suppose

map = Call java.util.Collections#emptyMap
Call map size

it fails miserably with:

Caused by: java.lang.IllegalAccessException: class io.jans.agama.engine.service.ActionService cannot access a member of class java.util.Collections$EmptyMap (in module java.base) with modifiers "public"
	at jdk.internal.reflect.Reflection.newIllegalAccessException(Reflection.java:392) ~[?:?]
	at java.lang.reflect.AccessibleObject.checkAccess(AccessibleObject.java:674) ~[?:?]
	at java.lang.reflect.Method.invoke(Method.java:560) ~[?:?]
	at io.jans.agama.engine.service.ActionService.callAction(ActionService.java:146) ~[agama-engine-1.0.21-SNAPSHOT.jar:?]

This is because the class returned is a sort of inner class (java.util.Collections$EmptyMap) and its size method is not accessible by external code - the method enforces access control despite it's public

Same issues occur when trying to Call methods on objects returned by Calls like java.util.Map#of ... and similar

Case 2. Suppose

package co;

public class SubTest extends Test {
    ...
}

...

package co;

public class Test {

    private String id;

    public String getId() {
        return id;
    }
    ....
}

and

obj = Call co.SubTest#new
Call obj getId

It fails with NoSuchMethodException: Unable to find a method called getId with arity 0 in class co.SubTest

The implementation is not scanning methods in the parent class

Case 3. A call like

Call one.two.three#new

Crahes with InvocationTargetException if the underlying constructor throws an exception. It should throw the original exception without wrapping it

[jgomer2001]

case 4. A call like

Call p method param

where p is an unknown (unset) variable in the flow, degenerates in attempts to lookup method on the String class.

This seems to be that way because an instance of org.mozilla.javascript.Undefined is received, and the getClass method on it seems to give String.

case 5. A call like

s = "a string"
Call instance method s

where method has param of type char[] or Character[] fails. The conversion is only succeeding when the param is exactly CharSequence, String or char
