When the syncer restart or an issue is synced there is a date field which is written before the
real data of the issue. Any updated to that date triggers a notification by Jira that the ticket change, but in fact the issue didn't change at all.

The syncer should avoid totally manipulating the issue data otherwise the syncer will
not be taken as a reliable one because all kind of weird issues and behaviours will be raised
and it will be hard to explain them. Syncing means keeping the same data - if we want
different presentation we should take advantage of Jira features for that.
P.S. the same goes for the new feature of markdown rendering
