[BUG] Out of gas causes panic when external contract store query executed

[yun-yeo]

Describe the bug
Core uses gas meter to limit unexpected query DDoS attacks to protect node operators from the external contract query. However, gas meter was made for Tx execution process, so it just occurs panic instead of clean error.

To Reproduce
set query_gas_limit = 0 in wasm.toml and execute query contract-store

Context & versions
v0.4.0

(if applicable) suggested solution
Append recover statement before executing external query
