    remove v.eig item from capscale result

    wa.eig and u.eig already disappeared with rda changes.

    The result still has CA$imaginary.u.eig (scaled scores for
    imaginary axes). These are the only scores returned for
    imaginary axes.

    remove u.eig, v.eig and wa.eig items from cca.default

    The cca.object was documented in vegan 1.6-10 (Sep 26, 2005), and
    in that document we warn that there is "no guarantee" that these
    itmems will be kept in future release. In commit bddfea39 (Mar 5, 2013)
    we use harsher tone and said that the "item will be removed". However,
    that harsher text has not been in any release version so that this
    may be an abrupt change.
