uncomment test/../rateq.sml (Isabelle 2002 --> 2011)

WN120317.TODO dropped rateq:
# test --- repair NO asms from rls RatEq_eliminate --- shows error from 2002
# test --- solve (1/x = 5, x) by me --- and --- x / (x ^ 2 - 6 * x + 9) - ...:
investigation Check_elementwise stopped due to too much effort finding out,
why Check_elementwise worked in 2002 in spite of the error.
