Protected environment access dropdown code causes runtime error for users under PREMIUM license

Summary

Run project with Starter license. Navigate to Project=>Settings=>CI/CD - there is an error in the console related to access_dropdown.js and protected environments initialization as the element to which it is mounted does not exist. It works fine for Premium.

Possible fixes

Check that element to which the app is mounted actually exists.
