`polymer test --config-file` does not work.

[hastebrot]

Description

There is a discrepancy between polymer test --config-file and wct --configFile. As a result polymer test completely ignores the file given to it using --config-file.

• This does not work: polymer test --config-file wct-headless.conf.json.
• This works: wct --configFile wct-headless.conf.json.

Source code of the respective CLI option definitions:

• https://github.com/Polymer/web-component-tester/blob/38dad962a1e4145c885efe5a3ddc0eb6e69ea24a/runner/config.ts#L362-L365
• https://github.com/Polymer/polymer-cli/blob/189b3c04b6d7386f554649fdf30bc283e6a33496/src/commands/test.ts#L134-L139

This seems to be a bug in polymer-cli, not in web-component-tester.

Versions & Environment

• Polymer CLI: 1.6.0
• node: v9.8.0
• Operating System: macOS Sierra 10.12.6

Steps to Reproduce

Create wct-headless.conf.json:

{
  "suites": [
    "test/index.html"
  ],
  "environmentImports": [
    "test-fixture/test-fixture.html"
  ],
  "plugins": {
    "local": {
      "browserOptions": {
        "chrome": [
          "headless",
          "disable-gpu",
          "no-sandbox"
        ],
        "firefox": [
          "-headless"
        ]
      }
    }
  }
}

Run ./node_modules/.bin/polymer test --local chrome --local firefox --config-file wct-headless.config.json.

Expected Results

Should run browsers in headless mode.

Actual Results

Does run browsers with window, i.e. ignores the config file. It works, when I rename wct-headless.config.json to wct.config.json. It complains when I use --configFile instead of --config-file. It does not complain when I give an unexistent file, e.g. --config-file wct-foobar.config.json.
