No reward trials somehow still have reward_time listed

[rachelstephlee]

Related to the #49, sometimes unrewarded trials will have a reward_time listed.

This is found by:

buggy_trials = nwb.df_trials[(nwb.df_trials['reward'] == 0) & (~np.isnan(nwb.df_trials['reward_time']))]

buggy_trials[['reward', 'animal_response', 'reward_time', 'reward_outcome_time']]

Note that the animal_response isn't 2, which means no response, for these trials, so isn't that the animal didn't respond and somehow got a reward_time recorded.

The trials that have this issue drop dramatically if we use the correct goCue timing for t0 in #49.
