Too long queries

theese tests performed on HAfAH takes too much time:

FAILED tavern/account_history_api_patterns/enum_virtual_ops/border_between_blocks.tavern.yaml::Hived

Here is curl from first one:

time curl -s --data '{"jsonrpc":"2.0", "method":"account_history_api.enum_virtual_ops", "params":{"block_range_begin": 2889020, "block_range_end": 2889021, "operation_begin": 3846274, "limit": 150}, "id":1}' http://localhost:8095
