remove url escape icq

[asalzmann]

Summary
Upgrading from ibc-go 7.2.0 -> 7.3.1 caused ICQs to fail with the following error

dockernet-stride1-1  | 7:35PM INF |   GAIA          |  VALIDATOR ICQCALLBACK  |  Inclusion proof validated - QueryId cd2662154e6d76b2b2b92e70c0cac3ccf534f9b74eb5b89819ec509083d00a50 module=x/interchainquery

The issue is in modules/core/23-commitment/types/merkle.go. Looking at the diff in merkle.go between those releases, we see that GetKey no long URL escapes merkle paths.

cosmos/ibc-go@v7.2.0...v7.3.1#diff-dd94ec1dde9b047c0cdfba204e30dad74a81de202e3b09ac5b42f493153811afR119

So, we also have to remove url escaping from Stride.

Relevant information from ibc-go: changelog and PR.

Also fixes a typo in the integration tests (@sampocs)
