so, now the problem is solved. I started to have also problems with gmail contacts which refused to sync with gmail. Syncing was so strange, it was duplicating 2 contacts every time in gmail ... grrr horrible.
Then I deleted all contacts in gmail, also all contacts in phone, I cleared the cache for google contacts app. Afterwards I restored contacts from my last .csv backup in gmail and after sync all contact were back in phone. I lost all photos of my contacts, so I had to link most of them with facebook contacts. But it solved the problem. The integration with facebook is working again
.. I was very happy yesterday
