This PR fixes some minor issues that I found in the main.py script. Namely: 1. The first observation was always all zeroes when using a generic agent. This is because the `update_environment_obs()` method is not called automatically and is only called by `env.reset()`. 2. The config yaml is never closed as the close function of the file reader was only referenced but never called. Related work items: #1441
