MySQL error after update to 2.7.0 (no replies)

I have updated my piwik instalation from 2.6.1 to 2.7.0 but there was some error during update. Piwik is still working but "core:archive" isn't and I am getting following error: Unknown column 'log_visit.user_id' in 'field list'

Full output of console core:archive:

I have tried use this FAQ [piwik.org] to force DB upgrade and it runs without error but nothing changes.
