cannot read times after read_evoked_fieldtrip

Hello,
When I load data using mne.read_evoked_fieldtrip, I am not able to read times, I added tmin value in the function by reading it from the fieldtrip structure as follows.

time= np.squeeze(ft_struct['time'])
tmin = time[0]

info = _create_info(ft_struct, info)  # create info structure
data_evoked = ft_struct['avg']  # create evoked data
evoked = EvokedArray(data_evoked, info, comment=comment, tmin=tmin)

This works fine and I am able to plot the data as expected. However, to do baseline correction in this evoked data, I had to add one hack to read_evoked_fieldtrip function:

  if(comment==None):
       comment = ' '

If I don't do this any evoked method that reads the comment field gives error: object of type 'NoneType' has no len().
This error is coming from the following patch:

   def __repr__(self):  # noqa: D105
       max_comment_length = 1000
       if len(self.comment) > max_comment_length:
           comment = self.comment[:max_comment_length]
           comment += "..."

Start at mne.read_evoked_fieldtrip and inspect the EvokedArray construction shown in the issue, including tmin and comment handling. Reproduce the reported time-reading and None-comment errors, then verify that imported evoked data retains its times and evoked methods can handle an omitted comment.
