Secondary indexes for JSON attrs sometimes don't work with string arrays

[glookka]

Bug Description:

Secondary indexes for JSON attributes sometimes don't return proper results with string arrays like

{"names":["data1", "data2", "data3"]}

and queries like

select *, in(j['names'], 'data1') as a from test WHERE a=1;

The issue happens when filters are transformed, but SI iterators are not spawned (e.g. when the index is too small). As SI are not used, transformed filter doesn't process string arrays correctly.
