Comparing Rational PMC to Integer PMC with == blows up

[dukeleto]

parrot_shell 1> loadlib $P1, 'rational'
    new $P2, 'Rational'
    new $P3, 'Integer'
    $P2 = "2/1"
    $P3 = 2
    if $P2 == $P3 goto pass
    ok(0,'== on Rational and Integer PMC')
    .return()
  pass:
    ok(1,'== on Rational and Integer PMC')

This patch should fix the issue; looks like a temporary Rat was created for the comparison, but then a non-existent attribute on the Integer was used instead.
