Add photo hash mismatch to avatar logs

If photo hash is advertized in presence and the photo hash is not yet known,
vcard is being requested. After vcard has been received at least two failures
can occur:
- there is no photo at all;
- photo has different hash than advertized.
Let log them for quick identification
