0.9.5.45: COMPUTE-RESTARTS with :TEST & no condition
 * COMPUTE-RESTARTS should return all restarts, even those with a test-function,
   when invoked without a condition. (RESTART-BIND describes test-function as
   accepting a condition, so we can't legally pass NIL in anyways -- the sane
   alternative seems to be to skip this filtering when computing restarts without the
   condition.)
