[Docs] A small mistake in the example of TimelineClient

I'm trying to use timeline client, then I copy the example into my application.
But there is a small mistake here:

myDomain.setID("MyDomain");
.....
myEntity.setEntityID("MyApp1")

The correct one should be

myDomain.setId("MyDomain");
.....
myEntity.setEntityId("MyApp1");
