Fix PREWHERE with row-level filters (when row filter is always true/false)
...
In case of row-level filters optimized out, i.e. converted to
always true/false, it is possible for MergeTreeRangeReader to reuse
incorrect statistics for the filter (countBytesInResultFilter()), and
because of this it simply does not apply other filters, since it assume
that this filter does not need to filter anything.
Fixes : #40956
