fix(devx): spell two self-test fixtures so they are not command-id literals

`check:cli-command-ids` reads any quoted run opening with a real oclif bin name
as a command-id literal, and reds when it resolves to nothing. Two fixtures in
the new parity gate's self-test were deliberately-unresolvable phrases.
