backport: Fix invalid minUnbondingTime for verifying inclusion proof (#…
…289) (#290) The bug is caused due to setting `params.MinStakingTime` to the btcstaking module's keeper method `VerifyInclusionProofAndGetHeight` other than `params.MinUnbondingTime`. In the fix, we remove `minUnbondingTime` from the parameter list of `VerifyInclusionProofAndGetHeight` as it should retrieve the parameter within the method. This PR also added comprehensive tests for `VerifyInclusionProofAndGetHeight`
