[Mne_analysis] morph to volume source after apply_lcmv_epochs

[Eric Larson]

        External Email - Use Caution        

`apply_lcmv_epochs` returns a list of STCs, not a single STC:

https://martinos.org/mne/stable/generated/mne.beamformer.apply_lcmv_epochs.html

So you probably want to iterate over them and morph each one, e.g.:

stcs_fsaverage = [morph.apply(stc) for stc in stcs]
