[slow sign in] Denormalize last-clock-value
In order to get `:last-clock-value` one extra query was executed for
each chat during initialization.

Implementation:
- `:last-clock-value` field was added to `chat` entity
- this field is updated when the message is sent/received
- extra query was removed
