Using fixed version totally makes sense, but tests fail

on simapp/app_test.go line 213 you need to add: mockModule.EXPECT().ConsensusVersion().Times(1).Return(uint64(0))

somehow the autogenerated mocks were edited manually, and not regenerated.

Oh, yes I used wrong number in description. Should be: #9282 (already updated).

There is something wrong here: this tests can't pass because in the last case the ante chain is not even called (sdk.ChainAnteDecorators return a decorator, but we still need to call it).

I added a call but we can't correctly check the mockAnteDecorator2 as a expected argument - see the note in the code.

The next is not called in a generated code. So we have to customize the code. Since the test was not functioning, this function never worked as expected.

SOLUTION: I'm removing types_handlers from auto - generated code.

@fdymylja - you were looking at the mocgen - did you solve it in any other way?
