Title: FIX: Fewer testing warnings

I had two warnings when running nosetests that I thought we could address pretty easily.

@mluessi, I was getting this warning with connectivity.py:
```
Test frequency-domain connectivity methods ... /home/larsoner/custombuilds/mne-python/mne/connectivity/spectral.py:616: RuntimeWarning: invalid value encountered in greater
if np.any(fmin > fmax):
```
See if you think my proposed changes are okay.

@dengemann, the other one was in ICA, but it seemed harmless:
```
Test additional functionality ... /home/larsoner/.local/lib/python2.7/site-packages/scipy/stats/morestats.py:776: UserWarning: Ties preclude use of exact statistic.
warnings.warn("Ties preclude use of exact statistic.")
```
Let me know what you think.
