TST: Disable talib default params test.

The data zipline_transform.window is always evaluating to empty,
thus the actual checks are not being used because of the
`if not data` done before running the `asserts`.

This behavior should be fixed, and we should either remove the
`not data` check, or bubble up that the check is being hit too
many times; but in the meantime, disabling this test which takes
a non-trivial amount of time to run.

When run as an algorithm, outside of unit tests the talib wrapper
does work, so the cause of the window always being empty may be to
due to the machinery of the unit test.
