Trigger dependencies broken after merge with ZBXNEXT-512

In a ZBXNEXT-512 (trunk revision 15246) have removed a column dep_level from the table triggers.
After these changes any actions with dependences of triggers cause errors GUI.

Example:
Error in query [UPDATE triggers SET dep_level=dep_level+1 WHERE triggerid=100100000013140] [Unknown column 'dep_level' in 'field list']
