Subject: [PATCH] Don't sync db on every sync
This fixes some lag, when Nheko is running, which could affect Nheko and
even other applications by excessively calling fsync. This should be
fine, since all filesystems seem to guarantee order and in most cases,
the modified pages are still written. In the worst case we should only
lose the last /sync results or similar.
