[RLlib] Fix test case test_envs_that_crash.

[sven1977]

Fix test case test_envs_that_crash.

Broken due to

• new AlgorithmConfig settings (some were recently renamed).
• Noticed that ignore_env_runner_failures (fka ignore_worker_failures) was NOT settable via any method of AlgorithmConfig (property had to be set manually since at least a few ray releases). Fixed now.

Why are these changes needed?

LGTM. No much change mainly renaming.
