FACES-1993 prepend ids of PartialVisitContext(s) with portlet namespace

> I wonder the same thing.

> [`findComponent`](http://docs.oracle.com/cd/E17802_01/j2ee/javaee/javaserverfaces/1.2_MR1/docs/api/javax/faces/component/UIComponent.html#findComponent(java.lang.String)) expects and checks for a leading separatorChar for better or for worse.
I am concerned about subsequent calls to findComponent using these ids,
which may no longer work because, with the change you are suggesting, there
would "never" be a leading separatorChar.

Okay leaving it the way that it is makes sense to me after reading the `findComponent()` docs. If the algorithm functions as they say, it seems like it should work as is. Thanks @vsingleton.
