FIX PCA error handling for invalid n_components
...
n_components < 0 was silently handled like None; > n_features gave a
cryptic error message from the bowels of np.linalg.
XXX n_components == 0 is still allowed as changing it makes tests fail,
not sure what it means.

FIX: np.abs might not work on scipy.sparse matrices
...
On current scipy master np.abs(X) triggers:
TypeError: __numpy_ufunc__ not implemented for this type.
I don't know if this is really a bug in scipy or not but in the mean
we can workaround this limitation as this is only for a test anyway.
