What is the current behavior?

In some cases xml-namespace-loader would add/register a global module without a suffix pointing to the xml file - which is incorrect because no-extension modules are reserved for code modules (ts/js). This resulted in the wrong context being passed to the custom component and failing to bind properly.

What is the new behavior?

We should now detect the "fallback" case - and not register the extensionless modules pointing to the xml files.

This partially fixes #9730 - when using a <Button> the taps are correctly handled by the parent context handler. For some reason, unrelated to this as far as I can tell, the tap event is not emitted from the <Label> inside the ActionBar.
