Tagir Valeev cee88f887b FindFirstMigration: use ifPresent when stream element type is primitive and the final statement is an assignment
This case is possible only if we have no non-final locals updated in the loop, so the assignment updates field or array element.
Using common assignment scenario may not work as primitive optionals lack map/filter operations
