chat: get rid of ChatId.is_error()

Browse Source 
get_rowid should not return 0, as we have inserted a row right above.

And using is_error() instead of comparing row_id to 0 is a strange way
to check this condition.

As all functions that actually returned 0 chat ID to indicate error have
been removed, the function is gone too.
