Created Unassigned: Allow syncing with shared databases on OneDrive [430]

user report:
if I create and own a directory and file then sync, save etc all works fine. If I am not the owner but can contribute and edit then the sync fails so cannot update from Android. Easy to recreate, get someone to create a directory and db on their OneDrive, send you the link and permissions to edit, open said db in keepass2android, sync and it will fail.
