OAuth request elements are duplicated in the API console and API request panel #678

Current examples of element and standalone API console include oauth1-authorization and oauth2-authorization handlers in both, the API console and the api-request-editor component which results in OAuth-related request events fired twice.

Expected outcome

OAuth request handlers should be included in either the API console or the request editor.

Actual outcome

OAuth request handlers included in both elements.

Steps to reproduce

1. Clone the git repo, run npm i and npm start after the installation.
2. In the opened browser tab, open the "API console as a standalone application" link or the "API console as a web component" link.
3. Open any API endpoint method and open the request panel.
4. Inspect the page code in browser's developer tools and search for <oauth2-authorization. See two entries instead of only one.
