Saving the dialog with `functional` = `always active` settings saves the value `false`

Problem/Motivation

Saving the dialog with functional as always active settings sets the group's value to false.

Agreeing the dialog sets the value functional to true.

Steps to reproduce

1. Enable module.
2. Saving with functional group enabled.
3. Reloading the page, via browser tools, inspect cookiesjsr value after decoding.

Proposed resolution

Should be set true in both cases.
Only “Decline” should set always active group values to false
