[da1suk8]

Description

Fixed from AccAddressFromBech32 to MustAccAddressFromBech32.
MustAccAddressFromBech32 has error handling.

https://github.com/line/lbm-sdk/blob/4250dfb146e92af16698d1359be413fa5b5158ff/types/address.go#L158-L165

The test was modified in reference to below.
https://github.com/CosmWasm/wasmd/blob/ccb2fdd0b6ed849eb94d58e0174f4fc34bce336c/x/wasm/keeper/keeper_test.go#L520-L524
(Here, the appropriate comparison was not made.)

Motivation and context

Since AccAddressFromBech32 does not have error handling, MustAccAddressFromBech32, which has error handling, was used.

How has this been tested?
