Remove cosmrs from osmosis-test-tube and only relying osmosis-std types

[iboss-ptk]

Reason being, cosmrs types don't derive serde and osmosis-std now have ability to generate types from cosmos module.

potential blocker: osmosis-labs/osmosis-rust#52

Problem

• osmosis-std struct requires implementing Serialize & Deserialize but tendermint_proto's structs do not implement them, so whenever there is a struct that depends on tendermint_proto, it will cause compile errors
• it maps tendermint related struct to tendermint_proto by this line
• This hack is used to skip struct that depends on tendermint_proto to suppress compiles error.

So that maybe not all of them can be replaced at the moment, only case by case, unless the blocker is resolved.
