While uploading a new folder, if the folder is renamed on the server
when still uploading, the result will be that the files that are already
uploaded will end up in the new filder name, but the file that were
not still are in the old folder.
After renaming, all the new uploads wil fail with an error on this sync
because the parent directory don't exist.
But they were uploaded with the old name in the next sync because
the renaming was not detected because the file id was not in the DB
Fix the problem by fetching the file id always when creating a new
directory, on the next sync, and saving it in the database ummediatly
https://github.com/owncloud/enterprise/issues/191
We fetch the id from the server, but don't save them in the database.
I Could have used INSTRUCTION_UPDATED for that, but then i would need to update the
reconcile algorithm to take in account the fact that UPDATED is possible there.
Instead, use should_update_etag which means the db is going to be written again
Remove reference to old instruction _UPDATED and _DELETED which does not make sens with
the new propagator
Improve the test to test this case, and that etags are properly writen to the DB
when there is a fake conflict
