hippotranslation virtual provider does not work directly below a hippo:facetselect

This is needed from hst pov: Typically, it would indicate which available languages there are in total

Typically, we have a node like:

/hst:hst/hst:sites/demosite-live/hst:content

where hst:content is a facetselect to the 'root content node'

Now, browsing into /hst:content, I get a leave node for 'hippotranslation:translations'

Browsing to the same hippotranslation:translations in the physical location, it does have child nodes for available languages.

I think is not a trivial bug, and hard to tackle. Typically, virtual providers like 'hippotranslation:translations' directly below a mirror have some corner case behaviour, which I stumbled on in the past as well.
