Fix refreshing of transcluded functions (#7698)

Browse Source 
* Passing test

* Failing test

* Fix test

It still fails, but now fails correctly

* Fix refreshing transcluded functions (#7755)

We store the previous result of the filter function and recalculate it
when the transclude widget needs to be refreshed, refreshing the widget
if the result is different.
