Title: FIX renamed what was `components_` to `sources_`

This PR fixes a bug I introduced in 02d1d85566bd8b6a35bc744d25b7b3a797f6a364.
There was already an undocumented attribute named ``components_`` that contained the sources.

This broke the whole thing.
Interestingly none of the tests found that, only noticed it through an example.

Should I add another warning that the meaning of ``components_`` changed?

That would be a warning that would be issued every time FastICA is used, though, as ``components_``
is used internally. This would be quite ugly.
