Remove test for safety configuration of cops documented with @safety YARD tag

[ydah]

This is because in some cases, even when a safety tag is present, safe may be false or set_autocorrect may be true.

  	# @safety
  	# The autocorrect is experimental - use with care! It can be configured
  	# with CustomTransform (e.g. have => has) and IgnoredWords (e.g. only).
  	#
  	# While the autocorrect will not break your code (it only modifies test
  	# description strings, not the actual test logic), it may produce
  	# grammatically incorrect English in some cases. Always review the diff
  	# when using autocorrect to ensure the descriptions remain natural and
  	# accurate.
  	#
  	# This is not classified as an unsafe autocorrect because it does not
  	# affect code behavior, but manual review of changes is strongly
  	# recommended.

Before submitting the PR make sure the following are checked:

• Feature branch is up-to-date with master (if not - rebase it).
• Squashed related commits together.
• [-] Added tests.
• [-] Updated documentation.
• [-] Added an entry to the CHANGELOG.md if the new code introduces user-observable changes.
• The build (bundle exec rake) passes (be sure to run this locally, since it may produce updated documentation that you will need to commit).

No objections on merging as is. Though, isn’t this a helpful poka-yoke? Maybe we could exclude some cops by marking them as “@safety tentative” in their docs and filtering those from participating in this spec?

Thank you!
