Mne-python: report does not work for toy example

[jasmainak]

If I do this on master:

from mne import Report
import matplotlib.pyplot as plt
rep = Report()
fig = plt.plot([1, 2], [1, 2])
rep.add_figs_to_section(fig, 'my caption')

it fails with the following message:

---------------------------------------------------------------------------

      3 rep = Report()
      4 fig = plt.plot([1, 2], [1, 2])
----> 5 rep.add_figs_to_section(fig, 'my caption')

oups @GuillaumeFavelier we broke something :(

can you have a look? or maybe @jasmainak you can find the fix quickly?

sorry it's a false alarm, plt.plot() does not return a figure object.

Nothing to worry :-)

It should raise an error if not a mpl or mayavi figure
