Should ContextInternal#isRunningOnContext cognize DuplicatedContext?

### Version

4.3.7

### Context

Test wheather a code is running on the same context of an vertical context.

### Do you have a reproducer?

Yes

### Steps to reproduce
The current
```java
default boolean isRunningOnContext() {
return current() == this && inThread();
}
```
in DuplicatedContext is not override by DuplicatedContext.

And the current DuplicatedContext has removed its own TaskQueue, and the javadoc seems need an update too.
