Rename from and fix rpc builder (#8)

* Fixed RPC builder, removed testing framework

Fixed a bug with the RPC builder setting the query builder's method to the RPC's schema.

Added a test for RPC functions.

Removed unnecessary testing framework.

Updated README.md

* Add Test for RPC function call

* Fix RPC builder bug

RPC builder was passing `schema` to the `method` property.

* Rename `form` to `from`

* Update PostgrestBuilder.swift
