Besides VM stack item limit we also have restrictions on the size of
JSON for a stackitem, which is 128k. This limit is much harder to
calculate, because JSON representation includes type and the encoding is
different for different items. Thus is makes no sense to invent our own
default, so use the one provided by neo-go. But for container listing we
know exactly what we process, so use big enough value, which is tested.
