The precision of sqlites datetime() timestamp is only one second (see https://www.sqlite.org/lang_datefunc.html). Therefore we could not order revisions of one note that were created in the same second. To remedy this, the primary key was changed to a monotonically increasing number, which solves the ordering problem. Signed-off-by: David Mehren <git@herrmehren.de>
