Title: cv::KalamFilter, updated predict()

Currently the predict function updates statePost, but not errorCovPost. As a result, the uncertainty does not grow if one keeps calling predict() without correct(). If this PR is accepted then this old ticket should be closed https://code.ros.org/trac/opencv/ticket/1380.
