* move file name/UID generation from SyncManager to LocalContact, LocalEvent, LocalTask
* rename updateFileNameAndUID() to prepareForUpload()
* use random UUID for contacts, UidGenerator with Android device ID for events/tasks
* LocalEvent.prepareForUpload(): use existing UID_2445 if available
Commit 5d1c90dcba fixed a bug where
entries added from the server were marked as "local only" (null etag)
which was causing issues. That commit fixes it for newly added resources,
but existing resources remained broken.
This commit goes through the database and fixes all of the existing
broken resources. It skips dirty entries because figuring out if they
were just created or updated is complex, and the chances of doing an
update at exactly the same time there are dirty entries is quite low,
so the complexity involved is just not worth it.
I was trying to avoid it, and keep it as davdroid both for attribution,
and making it easy to cherry-pick fixes from DAVdroid.
However, it seems to be causing clashes with the davdroid app, although
every piece of documentation claims otherwise.[1]
At least it seems like cherry-picks can still be achieved using:
git cherry-pick -s recursive -X find-renames=30 COMMIT
