REST Client Oddities

[alexanderbez]

Oddity 1

Start a localnet with a REST client listening. Any POST request will result in:

{
    "error": "http: request body too large"
}

Digging into the Go source code, I see MaxBytesReader is called. However, it's called with a max size of 0. Furthermore, even if I manually set MaxBytesReader in ReadRESTReq, I notice the constructor gets called TWICE and not only that, but the first time N is 0! It's as if the handler is being executed twice.

1. Why is MaxBytesReader being called twice?
2. Why is the 1st call being invoked with N: 0?

Note: This does not happen with the LCD tests

Oddity 2

While updating Gaia to use the latest SDK master, I noticed certain queries in the LCD tests internally had stale CLIContext values. Namely, the height.
