Add CheckPoints or SafePoints to DDBB

[CesareDj]

If the PC automatic restarts or daemon shut downs inmediatly without a propperly close, DDBB could be corrupted. Will be nice to have a Check point every 10 minutes (for example) to have a "return point" if the DDBB is damaged.

For example, if you click on the tab "complete node" and is not sync (red), we could have a button where the app restarts in the last recorded good point.
