RoomSimulator tries to load incorrect resource.

Hi, I am trying to debug the evaluation code for UNREAL agent (https://github.com/minosworld/unreal), which doesn't seem to work with the latest MINOS master branch (Updated after #135 )

I tried to isolate the problem, that is, ran the following snippet, which copies the same behavior from evaluate.py (create environment, which is creating a room simulator):

 args = sim_args.parse_sim_args(parser)
 args.visualize_sensors = True
 env_args = {'episode_schedule': 'test',
                'log_action_trace': True,
                'max_states_per_scene': 10,
                'episodes_per_scene_test': 1}
args.update(env_args)
sim = RoomSimulator(args) 
obs_space = sim.get_observation_space(args['outputs']) # hangs ---- infinite loop waiting for sim.start(), in new_episode.

And looking in the logs (simserver.log):

Surprisingly, the following snippet works without problems:

args = sim_args.parse_sim_args(parser)
args.visualize_sensors = True
sim = Simulator(args) # dumped args to a json file and compared them, for both RoomSimulator and 
# Simulator -- no differences, except for port and aparently nothing else relevant
common.attach_exit_handler(sim)

sim.init()
curr_schedule = 'test'
ep_schedulers = common.create_episode_schedulers(args)
test_ep_scheduler = ep_schedulers['test']
test_ep_scheduler.reset()
ep_settings = test_ep_scheduler.next_episode()

config = dict()
config['scene'] = {'fullId': args['scene']['dataset'] + '.' + ep_settings['scene_id'],
                   'level': ep_settings['level'],
                   'textureSet': curr_schedule}
config['goal'] = {'type': 'position', 'position': ep_settings['goal']['position']}
config['start'] = ep_settings['start']

sim.init()
sim.seed(0)
sim.configure(config)
ep_info = sim.start()

Any hints on how to solve it? Many thanks in advance!
