Component id validation fails to handle event bubbling scenarios correctly
--------------------------------------------------------------------------

                 Key: TAP5-1745
                 URL: https://issues.apache.org/jira/browse/TAP5-1745
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.3
            Reporter: Ville Virtanen
            Priority: Blocker


TAP5-1596 added component event handler validation to check that component actually exists
that can trigger the event that listener listens to. This functionality fails if the component
throwing the event is not in the template that declares the listener - thus event bubbling
is not possible anymore.

I have:
Page
 - MyComponent
   - Form t:id="myForm"

If the validation is disabled (using configuration.add(SymbolConstants.UNKNOWN_COMPONENT_ID_CHECK_ENABLED,
"false");) I can declare event listener "onFailureFromMyForm" and everything works as expected.

When the validation is enabled I get the exception "Method Page.onFailureFromMyForm() references
component id 'MyForm' which does not exist.". This is obviously wrong and the check algorithm
should check the WHOLE component tree if there is such an id.
