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).
