occ file:scan set the change date of directories
we see this behavior at owncloud version 10.0 and 10.5 at the web-ui.
Steps to reproduce:
view web-UI: Last change on mydirectory 1 year ago
occ file:scan --path=myaccount/mydirectory (no file was changed)
view web-UI: Last change on mydirectory now
After running Files:Scan, these change-date of directories didnt changing.
After running Files:Scan, all directories which was included changed changetime to now.
The user didnt see anything why (eg. activitiy log) and what was changed.
