can't get plugin rules by CLIEngine#getRules

Tell us about your environment

• ESLint Version:
  6.0.0

cli.getRules().get(ruleId) used can get plugin rule, now not.

Is this by design or a bug?

new (require('eslint').CLIEngine)().getRules().has('yoda')
// -> true

new (require('eslint').CLIEngine)({plugins: ['unicorn']}).getRules().has('unicorn/no-process-exit')
// -> false, should be true

After a few tries, I found after calling executeOnText or executeOnFiles, rules appeared, but calling getConfigForFile (which is I used before and works in #10838 ) plugin rules are not loaded.

Thank you for your report.

Sounds like a bug.

Yes, currently, it returns core rules and the plugin rules that the last execute* method call used.
