sorting bug found in 1.29:

1. sort the files in the library according to size

2. copy a new subfolder in a folder of the library, this new subfolder must have files that add to larger size than the largest sized already existing subfolder of the shared folder of the library

3. let fopnu hash the new subfolder

4. after hashing fopnu correctly displays the size of the folders but fails to re-sort them

5. the result is that with sort according to size from larger to smaller, the first folder is smaller than the subsequent new folder

6. what would be expected: fopnu should re-sort folders according to their new size after hashing
