MDL-32137 Fix message preference settings.
When a messaging output is set to forced, users should not be able to change
that. Regression intoroduced in bb3546f3 made possible to change checkboxes
(but not avoid forced settings). This fix replace checkboxes for 'forced'
settings with the corresponding message, similar to how it worked for
disallowed before.
