test: fix autotest list

This patch fixes a broken build; when running
make test
we get the following error:
...
Traceback (most recent call last):
  File "test/test/autotest.py", line 49, in <module>
    num_fails = runner.run_all_tests()
  File "test/test/autotest_runner.py", line 345, in run_all_tests
    self.parallel_tests)
  File "test/test/autotest_runner.py", line 264, in __filter_test
    test_cmd = test["Command"]
KeyError: 'Command'
...
The reason is that the pdump autotest entry uses "Comamnd"
instead of "Command"; this patch fixes it.
