Misconfiguration in TestGenesisTestSuite

[chatton]

Summary

Ref https://github.com/cosmos/ibc-go/pull/6721/files#r1664149748

The initial configuration that is supposed to be applied in this test was not actually being applied correctly, when refactoring the SetupSuite functions to apply this configuration, the test actually failed since the configuration was now being applied correctly.

What I noticed is that with a haltHeight of 100 hard coded, one of the chains ended up halting before the interchain account address could be created.

We need to double check this configuration and see does it need to be applied, or is the test fine without it.
