'AxesSubplot' object has no attribute 'hold' on nipype_preproc_spm_multimodal_faces example

When trying to run the nipype_preproc_spm_multimodal_faces example, I get the following error:

Traceback (most recent call last):

@Hororohoruru Could you please tell us if you don't see an error when you adapt the patch in PR #311
Thanks

Yes, that solves the issue.

Although after implementing those changes, I found another issue running the same example. I'll open a separated issue.

Never mind, I saw it was already reported on issue #287
