Revert "Related: tdf#147448 Scope owning mutex before it gets destroyed"
This reverts commit
dcd042c6f28276d707af409a87a1a4380398e9b0.
Reason for revert:
Revisiting, it was wrong to put that protector in its own scope because the actual mutex lock is only held in its ctor and it does SetAllowRefresh(true) in dtor, so while it exists it prevents other refresh timers to execute.
