Resolves: tdf#126928 allow link updates in an intermediate linked document
... if link updates are allowed in the current document and that intermediate document resides in a trusted location. This works with both, the "Always (from trusted locations)" and the "On request" settings under Tools -> Options -> Calc -> General. It can't work with documents residing in a non-trusted location as there is no way to allow updates on demand for a such loaded document (hidden via formulas).
