Remove a deliberately non-deterministic test

This test would pass if execution either succeeded or failed with a
EependencyError. It did not assert any relationship between those
two possibilities and whether earlier tasks actually succeeded or
failed.

test_fail_sequence in the same file tests more strongly whether a
failure is correctly propagated.
