The problem is: when I clock-in into some task and then within 1 minute
change tasks state to DONE, information about state transition recorded
incorrectly (:LOGBOOK: drawer is removed because of zero time, and then
state transition recorded out of drawer :LOGBOOK:).

I've next variables set to true: 
org-clock-out-remove-zero-time-clocks
org-clock-out-when-done
org-clock-into-drawer

Variable org-log-into-drawer set to "LOGBOOK"
