BUG: save beamformer filter

See original GitHub issue

Once we have done

filters = mne.beamformer.make_lcmv()

h5io isnt applicable because of the EmpiricalCovariance object

To be able to investigate this: how is the EmpiricalCovariance object obtained?

Looking at the code I don’t see why it would happen. @kingjr can you provide a snippet to replicate?

In the meantime @britta-wstnr you can proceed as if this is not an issue, assuming we will fix whatever is causing @kingjr to have the an EmpiricalCovariance rather than Covariance.

I hit this bug at some point, basically if you compute the cov on the fly it can have cov['estimator'] which is a sklearn object so you need to remove it before saving. I can tackle this I/O for 0.17
